Efficient stereocontrolled glycosidation of secondary sugar hydroxyls by silicon tethered intramolecular glycosidation
摘要:
Dissaccharides containing 1.2-cis glycoside linkages were synthesized by an efficient stereocontrolled two step process involving a silicon tethering step, to a dimethylsilyl acetal followed by intramolecular glycosidation with N-iodosuccinimide in nitromethane.
