5,6-tri- O -methyl- D - erythro -hex-2-enofuranose ( 4 ) was prepared by the action of lime-water on 2,3,5,6-tetra- O -methyl- D -glucofuranose ( 3 ). The α- D ( 6 ) and β- D ( 7 ) anomers of the methyl glycosides of 4 were obtained by methylation, and each was converted by methanolic acid into their anomeric mixture, and then into methyl 3-deoxy-5,6-di- O -methyl-α- and -β- D - erythro -hexofuranosidulose
摘要通过石灰水作用于2,3,5,6-tetra-O上,制备了3-Deoxy-2,5,6-tri-O-methyl-D-赤型-hex-2-enofuranose(4) -甲基-D-葡萄糖呋喃糖(3)。通过甲基化获得4的甲基糖苷的α-D(6)和β-D(7)异构体,然后分别通过甲醇将其转化为异头混合物,然后再转化为3-3-脱氧-5,6-甲基二-O-甲基-α-和-β-D-赤型-六呋喃糖苷二甲基缩醛(8和9)。5-(D-甘油-1,2-二甲氧基乙基)-3(2 H)-呋喃酮(5)是在4和6-9上的酸水溶液作用下形成的。改进了3及其甲基糖苷的制备方法。
