摘要
Iodonium ion (NIS/TfOH, cat.) assisted glycosylation of a sugar acceptor with properly protected ethyl(phenyl)-2-O-phenoxythiocarbonyl 1-thio-beta-D-gluco- or 1-thio-alpha-D-mannopyranoside donors gives the respective 1,2-trans linked 2'-ethyl(phenyl)thio-2'-deoxy-alpha-D-manno- or beta-D-glucopyranosides.
