【産業上の利用分野】
本発明は、光学活性マンガン錯体及び該マンガン錯体を使用するオレフィン化合物からの光学活性アジリジン化合物の製造法に関する。

【0002】
【従来の技術】
オレフィン化合物から光学活性アジリジン化合物を製造する方法としては、幾つかの金属錯体を触媒として使用する不斉アジリジン化反応が知られている。
例えば、J.Am.Chem.Soc.115,5328(1993)及びTetrahedron Lett.32,7373(1991)等のビスオキサゾリン−銅錯体を触媒として使用する反応、J.Am.Chem.Soc.115,5326(1993)のジイミン−銅錯体を触媒として使用する反応、Tetrahedron Lett.35,4631(1994)のビスアジリジン−銅錯体を触媒として使用する反応等が挙げられる。
