Abstract Peracylated glycofuranosyl isothiocyanates are obtained under smooth conditions starting from the corresponding glycosyl chloride by reaction with potassium thiocyanate in anhydrous acetone at room temperature, classical conditions for the synthesis of glycopyranosyl thiocyanates. In the case of furanoses, no glycosyl thiocyanates are obtained, and the procedure leads to the 1,2- trans isothiocyanates
摘要在正常条件下,由无水丙酮中的硫氰酸钾与相应的糖基氯反应,可在相应的糖基氯条件下,在光滑的条件下,于平滑的条件下获得过酰基化的呋喃呋喃糖基异硫氰酸酯,这是糖基吡喃糖基硫氰酸酯合成的经典条件。在呋喃糖酶的情况下,没有获得糖基硫氰酸酯,并且该方法立体选择性地产生1,2-反式异硫氰酸酯,产率超过80%。
