FIRST GLYCOSIDE SYNTHESIS VIA PIPERIDINIUM SALTS OF HETEROCYCLIC NITROGEN BASES: THE SYNTHESIS OF A NEW CLASS OF DIHYDROPYRIDINE THIOGLYCOSIDES

A first reported method for preparation of a new class of thioglycosides via reaction of piperidinium salts of dihydropyridinethiones with 2,3,4,6-tetra-O-acetyl-α-d-gluco- and galactopyranosyl bromides has been studied. Comparison with the products obtained from silylated thiopyridines is made.
