Description

【0001】
【発明の属する技術分野】
本発明は光学活性アミン誘導体の製造方法に関する。光学活性アミン誘導体は医、農薬合成中間体として有用な化合物である。
【0002】
【従来の技術】
従来、不斉ルイス酸触媒を用いて、光学活性β−アミノエステルを得る方法として、シリルケテンアセタールとイミンとの触媒的不斉マンニッヒ型反応等が知られている(例えば、非特許文献1参照)。一方、不斉ルイス酸触媒を用いて、α,β不飽和カルボニル化合物への窒素求核剤による不斉共役付加反応を高立体選択性で行った例は殆ど知られていない。
【0003】
また、不斉触媒を用いて、光学活性なα−カルボニルアジリジンを得る方法としては、例えば、D.A. Evans et. al., J. Am. Chem. Soc., 1993, 115, 5328.等のα,β不飽和エステルへの、N−トシルイミノフェニルヨージナンを用いた不斉付加反応が知られている。一方、この方法や他の方法で得られた光学活性なN−置換α−カルボニルアジリジンからN−無保護のアジリジンを得る方法は殆ど知られていない。
【0004】
また、不斉触媒を用いて光学活性なsyn−α−アミノ−β−ヒドロキシカルボニル化合物を製造する方法としては、直接これを得る方法としては、α−アミノ酸エステルのアルドール型反応を利用した方法(M. Horikawa et. al., 第42回天然有機化合物討論会講演要旨集,講演番号122(P−60))や、不斉水素添加反応における、dynamic kineticresolutionを利用する方法(Y.Hamada et. al. Tetrahedron asymmetry, 2001,12, 1757.)が知られている。また、不斉触媒反応で前駆体を製造し、この誘導によって、光学活性なsyn−α−アミノ−β−ヒドロキシカルボニル化合物を製造する方法としては、例えば、Y.Ito et. al., J. Am. Chem. Soc., 1986, 108, 6405.等のα−イソシアネートを用いたアルドール反応とその加水分解が知られている。また、アジリジンの開環により、anti−α−アミノ−β−ヒドロキシカルボニル化合物を製造する方法として、N−トシルアジリジンの酸触媒加水分解反応、(D.A. Evans et. al., J. Am. Chem. Soc., 1993,115, 5328.)が知られている。この中で、Y.Hamadaらの方法以外は、ジアステレオマーとしての異性体の混入が不可避である。

【発明が解決しようとする課題】
本発明の目的は、ジアステレオマーとして純度が高く、光学純度の高い光学活性syn−α−アミノ−β−ヒドロキシカルボニル化合物を製造するための一般的で簡便な新規の方法を見出すことである。更にこの製造の重要中間体となり得るN−無保護の光学活性なtrans−α−ケトアジリジンを用いる効率的合成法を見出すことである。そして更に立体的に高純度のこのアジリジンを効率的に製造するための新規な不斉触媒反応を利用する方法を提供することである。
【0007】
【課題を解決するための手段】
本発明者は上記課題を解決するため、
1.不斉ルイス酸触媒を用いた、アルキルオキシアミンを窒素求核剤とする高選択的共役付加反応を見出すこと、
2.そして、その生成物であるβ−アルキルオキシアミノカルボニル化合物を原料として、効率的にN−無保護の光学活性なα−ケトアジリジンを製造する方法を見出すこと、
3.更に、その生成物であるN−無保護の光学活性なα−ケトアジリジンを原料として、効率的に異性化を伴わずにsyn−α−アミノ−β−アミノカルボニル化合物を製造する方法を見出すために鋭意検討し、本発明を完成するに至った。

BACKGROUND OF THE INVENTION
The present invention relates to a method for producing an optically active amine derivative. The optically active amine derivative is a useful compound as an intermediate for medicine and agricultural chemical synthesis.
[0002]
[Prior art]
Conventionally, as a method for obtaining an optically active β-amino ester using an asymmetric Lewis acid catalyst, catalytic asymmetric Mannich type reaction of silyl ketene acetal and imine is known (for example, see Non-patent Document 1). ). On the other hand, few examples have been known in which an asymmetric conjugate addition reaction with a nitrogen nucleophile to an α, β unsaturated carbonyl compound is carried out with high stereoselectivity using an asymmetric Lewis acid catalyst.
[0003]
Examples of a method for obtaining optically active α-carbonylaziridine using an asymmetric catalyst include D.I. A. Evans et. al. , J. et al. Am. Chem. Soc. 1993, 115, 5328. An asymmetric addition reaction using an N-tosyliminophenyliodinane to an α, β unsaturated ester such as is known. On the other hand, there are few known methods for obtaining N-unprotected aziridine from the optically active N-substituted α-carbonylaziridine obtained by this method or other methods.
[0004]
In addition, as a method for producing an optically active syn-α-amino-β-hydroxycarbonyl compound using an asymmetric catalyst, a method using an aldol-type reaction of α-amino acid ester as a method for directly obtaining this ( M. Horika et.al., 42nd Natural Organic Compound Discussion Meeting, Lecture No. 122 (P-60)) and a method using dynamic kinetic resolution in an asymmetric hydrogenation reaction (Y. Hamada et. al., Tetrahedron asymmetry, 2001, 12, 1757.). Moreover, as a method for producing a precursor by an asymmetric catalytic reaction and producing an optically active syn-α-amino-β-hydroxycarbonyl compound by this induction, for example, Y. Ito et. al. , J. et al. Am. Chem. Soc. , 1986, 108, 6405. Aldol reaction using α-isocyanate such as, etc. and its hydrolysis are known. In addition, as a method for producing an anti-α-amino-β-hydroxycarbonyl compound by ring opening of aziridine, an acid-catalyzed hydrolysis reaction of N-tosylaziridine (DA Evans et. Al., J. Am. Chem. Soc., 1993, 115, 5328.). Among these, Y. Except for the method of Hamada et al., It is inevitable to mix isomers as diastereomers.

Examples 13 to 22 Aziridine ring formation reaction by base treatment of alkyloxyaminoketone
Under an argon atmosphere, sodium tertiary butoxide (0.1 M THF solution, 50 μl) was added to a solution of alkyloxyaminoketone (0.05 mmol) in dry THF (0.5 ml), and the mixture was stirred at room temperature for 1.5 hours. The reaction solution was directly passed through a small amount of silica gel column, and the eluate was concentrated and purified by silica gel column chromatography (hexane / ethyl acetate = 30/1 to 4/1) to obtain the desired product. The results are shown in Table 3.

Example 23, Example 24 Production of syn α-amido-β-hydroxyketone with aziridine ring opening
Under an argon atmosphere, a solution of trans-ketoaziridine (0.1 mmol) and triethylamine (0.2 mmol) in dry methylene chloride (0.5 ml) was added at 0 ° C. with acetyl chloride (0.2 mmol) in dry methylene chloride (0.2 ml). ) The solution was added dropwise and stirred at room temperature for 2 hours. After the reaction solution was washed with water twice, the organic phase was dried over anhydrous sodium sulfate and concentrated. This was purified by silica gel column chromatography (hexane / ethyl acetate = 2/1) to obtain the desired product. The results are shown in Table 4.
