Abstract
A novel process for producing an optically active amine is provided. The optically active amine is adapted for use as an intermediate in synthesizing physiologically active compounds such as pharmaceuticals and agricultural chemicals, as a functional material such as a liquid crystal, and as a starting material in synthesizing fine chemicals. The process comprises the step of reacting an imine with a hydride reagent in the presence of an optically active metal compound and an alcohol compound and/or carboxylic acid compound.
