Regio-and Stereoselective Synthesis of Oligosaccharides with Acetobromolactose and Acetobromomaltose as Glycosyl Donors Via Orthoester Intermediates
摘要:
Regio- and stereoselective synthesis of some trisaccharides was effected in high yields from coupling of acetobromolactose or acetobromomaltose as donors with partially protected glucoside accepters through an ortho ester formation-rearrangement strategy. Selective 1-->6 or 1-->3 with 1,2-trans glycosylation was achieved.
