Document Type and Number:
WIPO Patent Application WO/1997/045391
Kind Code:
A1
Abstract:
A process for preparing optically active alcoholic compounds wherein a carbonyl compound is asymmetrically reduced in an economical and practical manner. The process comprises treating a prochiral carbonyl compound represented by general formula (1) with an optically active organoaluminum compound represented by general formula (2) to conduct asymmetric reduction, thereby preparing an optically active alcoholic compound represented by general formula (3).
