Autor: Manabu Seno, Toshio Takido, Mitsutaka Chida, Takayoshi Fujihira, Haruo Kamijo
Publikováno v: Journal of Carbohydrate Chemistry. 21:287-292
Methanolysis of a glycosylthioiminium salt, which was prepared from the reaction of acetohalogenosugar with thioacetamide, afforded the corresponding per-O-acetylated 1,2-trans-1-thioglycose in good yield after fractional crystallization. This synthe
