There is disclosed an optically active salicylideneaminoalcohol compound of formula (1):wherein Rrepresents an alkyl group or the like, Rrepresents

Chiral copper complex and production processes thereof and using the same

There is disclosed are an enzyme preparation characterized by a polymer carrier having fine pores with average radius of 200-500 &#x212b; and the enzyme is capable of converting an N-substituted cyclic imino ester into an (S)-N-substituted cyclic imino acid, thereby an (S)-N-substituted cyclic imino acid is preferentially produced, and has an amino acid sequence as set forth in SEQ ID NO: 1 or the like.

Enzyme preparation and method of using the same

A process for preparing an optically active alcohol by reacting a prochiral ketone corresponding to the optically active alcohol and an acid with a mixture of (1) a boron-containing compound selected from the group consisting of i) a borane compound which is obtained from an optically active .beta.-aminoalcohol and a boron hydride; or obtained from the optically active .beta.-aminoalcohol, a metal borohydride and an acid and ii) an optically active oxazaborolidine and (2) a metal borohydride; and a process for preparing an optically active amine by reacting an oxime derivative and an acid with a mixture of (1) a boron-containing compound selected from the group consisting of i) a borane compound which is obtained from an optically active .beta.-aminoalcohol and a boron hydride, or obtained from said optically active .beta.-aminoalcohol, a metal borohydride and an acid and ii) an optically active oxazaborolidine, and (2) a metal borohydride.

Processes for preparing optically active alcohols and optically active

There is disclosed a process for the production of N-substituted carbazoles with high efficiency, in which a carbazole compound is reacted with an appropriate halogenated compound in an inert solvent in the presence of an acid-removing agent and an amine without using any quaternary ammonium salt which is required in the conventional process.
