Abstract: Anew method for the synthesis of 1-thio-glycosides using 1-O-trifluoroacetyl-2,3,4,6-te-tra-O-benzyl-a-D-gluco- or manna-pyranose with R'SHin the presence of Lewis acid is reported. The reaction conditions were very mild. 1-thio-a-D-glycosides 3a-e and 6a-c were obtained in high yields and a high stereoselectivity. Their structures were proved by IR,1H NMR, 13C NMR and elementary analysis.

Key words: Trifluoroacetyl hexopyranose, Stereoselectivity, Thioglycoside
