Stereoselective cis glycosylation of 2-O-allyl protected glycosyl donors by intramolecular aglycon delivery (IAD)
Abstract
2-O-Allyl protected glycosyl donors may be glycosylated stereoselectively via a three step sequence involving double bond isomerization, N-iodosuccinimide mediated tethering to a glycosyl acceptor and subsequent intramolecular glycosylation (intramolecular aglycon delivery, IAD).
