Abstract
Efficient synthesis of lauryl thioglycoside of Neu5Gc was accomplished from a known thioglycoside of Neu5Ac. The reactivities of the Neu5Gc thioglycoside for O-glycosidation by means of TMSOTf-NIS as a promoter system were investigated, and the thioglycoside showed good activities with simple alcohols. In addition to the simple alcohols, the reactivities of lauryl thioglycoside of Neu5Gc were also evaluated with glucose and lactose derivatives and the results suggested that the thioglycoside is a potential candidate for glycosidation as the glycosyl donor.
