Abstract Condensation of 2,4-di- O -acetyl-3,6-di- O -methyl-α- d -glucopyranosyl bromide with either allyl or benzyl 2,4-di- O -methyl-α- l -rhamnopyranoside in the presence of mercuric cyanide, followed by O -deacetylation, gave the title oligosaccharides in excellent yields.
摘要2,4-二-O-乙酰基-3,6-二-O-甲基-α-d-吡喃葡萄糖基溴化物与烯丙基或苄基的2,4-二-O-甲基-α-1-鼠李糖吡喃糖苷缩合。氰化汞的存在,然后进行O-脱乙酰基反应,可以极好的收率得到标题寡糖。
