Stereocontrolled glycosylation of sordaricin in the presence of ammonium salts
摘要:
The glycosidation of sordaricin with deoxy sugars derivatives was studied under acid-promoted conditions and by anomeric O-alkylation with sordaricin triflate. In both methods, an important effect of added ammonium salts on the stereoselectivity of the glycosidation was observed. (C) 2000 Published by Elsevier Science Ltd.
