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

摘要

An enzymatic process is disclosed for the preparation of galactosylβ1,3glycal disaccharides such as Galβ1,3Glucal, an intermediate useful in Lea preparation and an inhibitor of β-galactosidase. The process utilizes β-galactosidase, an enzyme usually used for bond breaking, to form a bond between a galactoside and a glucal such as glycal, a 6-0-C¿1?-C6 acylglucal or 6-0-C1-C6 acetylgalactal.
