Title:
PROCESSES FOR THE PREPARATION OF OPTICALLY ACTIVE KETONES
Document Type and Number:
WIPO Patent Application WO/1998/000382
Kind Code:
A1
Abstract:
Processes for preparing optically active esters by reacting racemic alcohols with optically active amino acid derivatives or optically active tartaric acid derivatives; processes for preparing optically active alcohols by hydrolyzing the esters; processes for preparing ketones by oxidizing the alcohols; processes for storing the optically active ketones stably; and novel optically active amino acid esters and optically active tartaric acid esters which are useful as the intermediates for the preparation of drugs or agricultural chemicals.
