Acidic glycosyl acceptors

A mixture of hemiacetal donor (1 mmol), glycosyl acceptor (1.2 equiv), methoxyacetic acid (0.1 equiv) and Yb(OTf)3 (0.1 equiv) in dichloromethane (40 ml) was... [Pg.147]

This method works very well for reactive glycosyl acceptors such as primary alcohols. It can be carried out without affecting other acid sensitive functionalities including acetonides and even orthoesters. Nishimura and co-workers successfully employed this method to prepare the ttisaccharide monomer 344 (Scheme 8.107). After deprotection, the product was copolymerized with acrylamide to give a biologically interesting glycoprotein model. [Pg.431]
