MILD AND SELECTIVE O-GLYCOSYLATIONS OF PRIMARY ALCOHOLS WITH THE THIOGLUCOSAMINIDE DERIVATIVE PROMOTED BY N-IODOSUCCINIMIDE AND HBF(4)-ADOSROBED ON SILICA GEL
{{output}}
Selective glycosylations of primary alcohols with the thioglucosaminide 1 are achieved by using NIS and HBF(4)-SiO(2). HBF(4)-SiO(2) is a mild Brønsted acid which requires primary alcohols or phenols to effectively activate 1 with NIS at rt. A wide range of f... ...
