Abstract Condensation of tetra-O-acetyl-α- D -glucopyranosyl bromide with 1,3,4,6-tetra-O-acetyl-α- D -glucopyranose in acetonitrile solution containing mercuric cyanide and mercuric bromide affords the octa-acetates of both kojibiose (2-O-α- D -glucopyranosyl- D -glucose) and sophorose (2-O-β- D -glucopyranosyl- D -glucose). Each of these products can be isolated in approximately 28% yield. Although
摘要在氰化汞和溴化汞的乙腈溶液中,四-O-乙酰基-α-D-吡喃葡萄糖基溴与1,3,4,6-四-O-乙酰基-α-D-吡喃葡萄糖的缩合可得到八乙酸酯曲二糖(2-O-α-D-吡喃葡萄糖基-D-葡萄糖)和槐糖(2-O-β-D-吡喃葡糖基-D-葡萄糖)。这些产物中的每一种都可以约28%的产率分离出来。尽管与替代方法相比,该方法从D-葡萄糖获得的槐糖总产量较低,但它具有更快,更直接的优势,特别适合于乙酰化糖基溴化物的制备。
