Stereocontrolled glycosylations via additions of sulfur electrophiles to glycals
摘要:
The methodology described herein examines the regio- and stereoselectivity of pyrimidine and purine glycosylations of furanoid glycals. The results show that following stereoselective sulfenylation, glycosylation of furanoid glycals, in the presence of SnCl4, Proceeds both regio- and stereoselectively.
