A Total Synthesis of a New Class of Biazine Thioglycosides

Abstract

A new method for the synthesis of bipyridinyl S‐glycosides 11 and 12 has provided the title compounds in a higher yield. Application of a one‐pot glycosylation methodology resulted in an efficient, high‐yield synthesis of biazine S‐glycosides 17–20 An X‐ray diffraction analysis of 11 disclosed the conformation of this glycoside as the S‐glycoside and not the corresponding N‐form.
