Hg(OTf)2-catalyzed glycosylation using alkynoate as the leaving group

A novel Hg(OTf)(2)-catalyzed glycosylation procedure has developed using alkynoic acid residues as the leaving group under mild reaction conditions and efficient catalytic turnover. The process is particularly useful for the glycosylation of hindered alcohols. (c) 2006 Elsevier Ltd. All rights reserved.
