Abstract
Abstract A new method for preparation of a new class of acrylamide thioglycosides via a one- pot reaction of potassium 2-cyanoethylene-1-thiolate salts with 2, 3, 4, 6-tetra-O-acetyl-α-D- gluco-and galactopyranosyl bromides has been studied. The E-configuration of these thioglycosides were proven by their transformations to the corresponding 5-aminopyrazoles.
