标 题 :Enantio- and regioselective synthesis of organic compounds using enol esters as irreversible transacylation reagents
发明人：WONG CHI-HUEY; WANG YI-FONG; HENNEN WILIAM J
权利人:SEARLE & CO
摘要:A process for irreversible regio- and stereoselective enzyme catalyzed acylation of alcohols using enol esters as acylating reagents is disclosed. The present invention permits the selective modification of hydroxyl group(s) of chiral and meso alcohols, including sugars, organometallics, and glycosides. The enol freed upon transesterification rapidly tautomerizes to the corresponding volatile aldehyde or ketone thereby preventing the reverse reaction from occurring.
