A FACILE ENZYMATIC SYNTHESIS OF GALACTOSYL-BETA-1,3 GLYCALS.

摘要

An enzymatic process is disclosed for the preparation of galactosyl beta 1,3glycal disaccharides such as Gal beta 1,3Glucal, an intermediate useful in Lea preparation and an inhibitor of beta -galactosidase. The process utilizes beta -galactosidase, an enzyme usually used for bond breaking, to form a bond between a galactoside and a glucal such as glycal, a 6-O-C1-C6 acylglucal or 6-O-C1-C6 acetylgalactal.
