Methyl 4,6-dideoxy-3-C-methyl-4-(N-methyl-N-phenylsulfonylamino)-alpha-L- mannopyranoside and methyl 4-amino-4,6-dideoxy-3-C-methyl-alpha-L-mannopyranoside, derivatives of the branched-chain amino sugars sibirosamine and kansosamine, respectively, were synthesized by nucleophilic ring-opening of methyl 3,4-anhydro-6-deoxy-3-C-methyl-alpha-L-talopyranoside. Catalytic reduction of methyl 6-deoxy-2,3
甲基4,6-二脱氧-3-C-甲基-4-(N-甲基-N-苯基磺酰基氨基)-α-L-甘露吡喃糖苷和甲基4-氨基-4,6-二脱氧-3-C-甲基-α- L-甘露吡喃糖苷是支链氨基糖西伯胺和甘露糖胺的衍生物,是通过甲基3,4-脱水-6-脱氧-3-C-甲基-α-L-吡喃葡糖苷的亲核开环合成的。催化还原甲基6-脱氧-2,3-O-异亚丙基-3-C-甲基-α-L-lyxo-己吡喃并sid-4-ulose生成轴向醇甲基6-脱氧-2,3-O-异亚丙基-3-C-甲基-α-L-塔洛吡喃糖苷,已知的绒毛糖前体。
