be a suitable glycosylating agent for the acid-catalysed, direct synthesis of O-, S- and N-glucofuranosyl compounds. Beta-linked products are formed with good selectivity. Reaction with cyanotrimethylsilane gave the 1,2-O-(1-cyanopropylidene)acetal rather than the C-glycosyl cyanide. By selective acid-catalysed hydrolysis, the title compound was converted to the 1-hydroxy analogue from which the trichloroacetimidates
容易获得的结晶五-O-丙酰基-β-D-葡萄糖呋喃糖被证明是用于酸催化的O-,S-和N-葡萄糖呋喃糖基化合物的直接合成的合适的糖基化剂。β-连接的产物具有良好的选择性。与氰基三甲基硅烷反应得到1,2-O-(1-氰基亚丙基)缩醛而不是C-糖基氰化物。通过选择性的酸催化水解,将标题化合物转化为1-羟基类似物,由此可制得三氯乙亚氨酸酯作为其他潜在的糖基化剂。
