Highly efficient synthesis of 1-thioglycosides in solution and solid phase using iminophosphorane bases

Xu, Weizheng,Springfield, Shawn A.,Koh, John T.

, p. 169 - 176 (2000)

Disaccharides of 1-thioglycosides, an important class of glycomimics, can be synthesized by direct S-alkylation in exceptionally high yields when iminophosphorane bases are employed. The reaction conditions employed appear to be general and stereospecific
