Description
AZIDIRINO DERIVATES OF TETRAMERIC CYCLOPHOSPHAZENES
The invention relates to an aziridino derivative of a tetrameric cyclochlorophosphazene compound.
The (NPCL2 ) -tetramer having the formula N4 P4Cl8 and the compound N4P4Az8 derived therefrom, in which Az is aziridino, are known from the article by V.A. Chernov, V.B. Lytkina, S.I. Sergievskaya, A.A. Kropacheva, V.A. Parshina and L.E. Sventsitskaya, Farmakol. Toksikol. (Moscow) 22, 365 (1959). Of the compound N4P4Az8 it is indicated that it has an anti-tumor activity with respect to S-45 sarcoma in rats. Moreover, Inorg. Chem. 3 (1964) 757-761 discloses that the compound N4P4Az8 can be prepared by complete aminolysis of the tetrameric N4P4Cl8 by means of aziridine or a homologue thereof in an aromatic hydrocarbon as reaction medium and triethylamine as acid acceptor. It is an object of the invention to provide an aziridino derivative of a tetrameric cyclochlorophosphazene compound which may serve as starting-material in the synthesis of tetrameric cyclophosphazene compounds to be derived therefrom and containing one or more aziridino groups by substitution of the chlorine atoms by a properly selected substituent, of which latter compounds it may be expected that they also have an anti-tumor activity.
For this purpose the invention provides a compound of the type defined in the opening paragraph, characterized by the formula N4 P4Cl8-nAzn, in which n = 1,2,3,4,5,6 or 7.
Although the preparation of the compounds according to the invention proceeds rather easily with good precautions, the isolation of different, mostly isomeric products is not easy. E.g. the reaction of (NPCL2) 4 with aziridine gives at a molar ratio of 1:3.5, mainly the 6 products N4P4Cl7AZ gem-N4P4Cl6Az2 1,3-cis-N4P4Cl6Az2
1,5-cis-N4P4Cl6,Az2
1,3-trans-N4P4Cl6Az2
1,5-trans-N4P4Cl6Az2,in addition to a number of products N4P4Cl5Az3 A schematic representation of the structural formulae of these compounds, in which the ring-N-atoms and the Cl-atoms have been omitted, is given by formulae 1-6 of the sheet of formulae.
In accordance with what has been stated in the preceding paragraph the invention therefore also relates to a process for preparing an aziridino derivative according to the invention by aminolysis in a reaction solution of a cyclopolychlorophosphazene compound and working up of the reaction mixture,which process is characterized in that in a compound having the formula N4P4Cl8-n Azn, in which n = 0,1,2,3,4,5 or
6, 1-7 chlorine atoms are substituted by an aziridino group and that the resulting aziridino derivative are recovered from the product obtained after working up of the reaction mixture by means of HPLC ("high performance liquid chromatography").
In the process according to the invention the selection of column material and eluent depends, within the scope of application of the HPLC technique, on the reaction mixture to be analyzed.
As will be elucidated hereinafter, the ratio of mono-aziri- dino to polyaziridino substitution is, e.g. in the case of starting from (NPCL2)4 ,the ratio in the reaction product of mono-aziridino to di-aziridino substitution, to be varied by affecting the molar ratio of the reaction components and, if required, the reaction time.
A suitable solvent in which the process according to the invention can be carried out is dry diethyl ether but also benzene, pentane, hexane and THF (tetrahydrofuran) are suitable for having reactions carried out therein.
The aziridino derivative of the tetrameric cyclochlorophosphazene compounds according to the invention are suitable starting materials for preparing compounds therefrom, the chlorine atoms being replaced by properly selected other substituents. In view of the teaching from later published Dutch patent application no. 83.00573 it may be expected that such compounds have an anti-tumor activity.
Consequently, the invention also relates to an aziridino derivative of a tetrameric substituted cyclophosphazene compound having an antitumor activity, characterized by the formula N4P4R8-nAzn, in which n = 1,2,3,4,5,6 or 7 and R represents the same or different substituents.
Preferably, R is an electron donating group of low sensitivity to hydrolysis.
The invention will be illustrated by the example given herein below. Example I
Preparation of N4P4AznCl8-n (n=l,2).
(NPCL2)4 (Otsuka Chem.) was recrystaliized from hexane before use. Aziridine was distilled from KOH pills under dry nitrogen just before use. Solvents were purified and dried in the conventional manner. Reactions were carried out under a dry nitrogen atmosphere. 31P and 1H NMR spectra were measured with a Nicolet 283A FT spectrometer equipped with an NTCFT1180 data system, in 10 mm tubes at 25°C. The deuterium resonance of the solvent (CDCl3) was used as "field-frequency lock". HPLC separations were carried out by using two Waters 6000A liquid pumps (each having a capacity of 20 cm3/min.) and a Waters R401 refractometer. Lichrosorb Si 60/10 served as column material.
A. Reaction of (NPCL2)4 with aziridine in the molar ratio of 1:2.5. A solution of 1.4 cm3 of aziridine (27.1 mmol) in 150 cm3 of dry diethyl etherwas added dropwise to a solution of 5.0 g of (NPCL2)4 (10,8 mmol) in 300 cm of dry diethyl ether for 30-45 min., while vigorously stirring and cooling to - 20°C. After the reaction mixture was warmed up slowly to room temperature and after a reaction time of 18 hours filtration of the polyaeric amino-HCL salt and evaporation of the filtrate gave 5.1 g of a white waxy oil which turned out to be slightly sensitive to hydrolysis (Product A) .
B. Reaction of (NPCL2)4 with aziridine inthe molar ratio of 1:3.5.
A solution of 3.9 cm3 of aziridine (77.8 mmol) in 100 cm3 of dry diethyl ether was added dropwise to a solution of 10.0 g (NPCL2)4
(21.6 mmol) in 400 cm3 of dry diethylether for 30-45 min., while vigorously stirring and cooling to - 0°C. the reaction mixture
was warmed up slowly to room temperature and stirred further until a total reaction time of 7 hours. The working up procedure as set forth below A. gave 10.5 g of a turbid oil sensitive to hydrolysis (Product B
C. Analysis of the products. Analysis of 31P NMR and mass spectra as well as HPLC diagrams
(Fig. 1 and Fig. 2) showed that products A and B had the same composition in principle. A especially contained N4P4AzCl7while B, in addition to this component, especially contained N4P4Az2Cl6 (namely 5 isomers). The ratio of mono/disubstitution was to be affected by varying the molar ratio and the reaction time. It turned out that a reaction mixture such as product B was also to be obtained starting from N4P4AzCl7, in a 1:2 reaction with aziridine in dry diethyl ether.
D. Separation methods
It turned out that both product A and product B could be separate with HPLC by using a 25% diethyl ether/75% hexane eluent. Product A give N4P4AzCl7as the largest fraction (Fig 1, fraction 1). In total, 2.56 g were obtained (yield 50%). Recrystalization from pentane gave 1.9 g of analytically pure material; melting point 68.5-70.0°C.
Under corresponding conditions product B gave seven fractions (Fig. 2) : Fraction no. : (1) N4P4AzCl7 1.54 g
(2) N4P4Az2Cl6 2.12 g
(3) " 1,26 g different isomers
(4) " 0,65 g
(5) N4P4Az2Cl6 1.63 g
Fraction no. : (6) N4P4Az3Cl5 different isomers
(7) N4P4Az3Cl5
Total 8.15 g = 77.8% on product B.
It turned out that fraction 5 consisted of 2 components which were once again separated afterwards with the same eluent (Fig. 3) .

Mass spectra
The mass spectra of both N4P4AzCl7 and N4P4Az2Cl6 showed different chlorine isotope peaks in addition to parent peaks of respectively M+ = 467 (for 35Cl) and M+= 474 (for 35Cl). The spectra of the different isomeric forms of N4P4Az2Cl6were not distinguishable.
Infrared spectra N4P4AzCl7gave a ring frequency at 1316 (broad) or 1279 cm-1 (sharp); the "aziridino" band lay at 965 cm-1 (sharp). The IR spectra of the isomeric compounds N4P4Az2Cl6 were clearly distinguishable. Ring frequencies varied from 1310-1334 cm-1 (broad) or from 1275-1279 cm-1 (sharp). Aziridino bands were visible from 963 to 976 cm-1 (sharp) .

Example II
Preparation of a number of aziridino derivative having the formula N4P4R8-nAzn.
In de preparation of the abovementioned aziridino derivative the resulting reaction mixture was worked up according to procedure (a) mentioned herein below:
Procedure (a)
Most reactions afforded considerable amounts of hydrochloride salts, either precipitated or in solution. The use of aziridine as a hydrochloride scavenger resulted in the aziridino chloride salt which is rather unstable andsubsequently polymerized.
Precipitated (polymeric) salts are removed by filtration and, after washing thoroughly with solvent, the combined filtrates containing, the P-N ring compounds are evaporated in vacuo. If acetonitrile or THF is used as solvent, the complete reaction mixture is evaporated in vacuo. Extraction with diethyl ether or benzene yields solutions of the salt-free crude products.
All crude products are purified by recrystallization from an appropriate solvent. Mixtures are separated by HPLC and the resulting fractions are subsequently recrystallized.
Preparation of N4P4AzAm7 and N4P4Az2Am6 (Am = NHme, NMe2, wherein me = methyl: compounds nos. 11-22): the compounds having formulae 1-5II of the sheet of formulae were used as starting compounds.
N4P4Az(NHMe) 7 and N4P4Az2 (NHMe) 6
To a stirred solution of 0,5 g (ca. 1 mmol) of the ring compounds in 15 cm3 of chloroform, cooled at 0°C, were slowly added 15cm3 of a
1 M solution of methylamine in benzene. After warming up to room temperature and a reaction time of 18 h application of procedure (a) afforded the crude products. There was obtained a white solid when the compound having formula 2 of the sheet of formulae was used as starting compound. In all other cases the products consisted of resinous oils. All compounds were reerystalilized several times from mixtures of diethyl ether and aiethylene chloride. When the compound having formula 5II of the sheet of formulae was used as starting material, a contaminated oil was obtained. Mass and NMR spectra indicated the presence of the completely aminol zed product. Further data are listed in Table I given herein below.
N4P4Az(MMe2)7 and N4P4Az2 (HMe2)6
To a stirred solution of 0.5 g (ca. 1 mmol) of the ring com- pound in 25 cm3 diethyl ether, cooled at 0°C, was added dropwise
15 cm3 of a 3 M dimethylamine solution in diethyl ether. After warming up to room temperature and a reaction time of 18 h, the working up by using procedure (a) yielded 0.57 g of an oily material. This was dissolved in 25 cm3 of diethyl ether -and refluxed overnight after adding 10 cm3 of a 3 M dimethylamine solution in diethyl ether. Subsequently,procedure (a) was once again used, yielding 0.54 g of a white solid (if the starting material is the compound having formula 1 or formula 2 of the sheet of formulae) or a viscous oil (if the starting material is the compound having formula 3 or formula 5II of the sheet of formulae). The solid was easily crystallized from hexane, whereas the oil required several recrystallizations from small amounts of hexane at -70°C. The product obtained by starting from the compound having formula 2 of the sheet of formulae remained an oil of unsatisfactory purity. Mass and NMR spectra were in agreement with the completely aminoIyzed compound no. 22. Further data are listed in table II given herei below.
