Abstract Efficient syntheses are described of the branched d -mannopentaosides methyl 2,6-di- O -(2- O -α- d -mannopyranosyl-α- d -mannopyranosyl)α- d -mannopyranoside and methyl 2,4-di- O -(2- O -α- d -mannopyranosyl-α- d -mannopyranosyl)-α- d -mannopyranoside, starting from the glycosyl acceptors methyl 3,4-di- O -benzyl-α- d -mannopyranoside and methyl 3,6-di- O -benzyl-α- d -mannopyranoside, and
摘要描述了高效合成支链d-甘露糖苷甲基2,6-di-O-(2-O-α-d-甘露吡喃糖基-α-d-甘露吡喃糖基)α-d-甘露吡喃糖苷和甲基2,4-二- O-(2-O-α-d-甘露吡喃糖基-α-d-甘露吡喃糖基)-α-d-甘露吡喃糖苷,起始于糖基受体甲基3,4-二-O-苄基-α-d-甘露吡喃糖苷和甲基3 ,6-二-O-苄基-α-d-甘露吡喃糖苷,并使用保护的d-甘露糖苷甲基3,4-二-O-苄基-2,6-二-O-(3,4,6-tri- O-苄基-α-d-甘露吡喃糖基)-α-d-甘露糖吡喃糖苷和甲基3,6-二-O-苄基-2,4-二-O-(3,4,6-三-O-苄基- α-d-甘露糖吡喃糖基)-α-d-甘露糖吡喃糖苷为关键中间体。
