The synthesis of methyl (methyl α-D-mannopyranosid)uronate and its 2- and 4-0-methyl ethers has been effected by the chromium trioxide oxidation of the corresponding O-benzyl and O-benzylidene derivatives of methyl α-D-mannopyranoside, esterification with diazomethane, and subsequent elimination of the protective benzyl or benzylidene groups by catalytic hydrogenolysis.
甲基(α-D-吡喃甘露糖苷)糖醛酸甲酯及其2-和4-0-甲基醚的合成是通过三氧化铬氧化相应的α-D-吡喃甘露糖苷的O-苄基和O-亚苄基衍生物来实现的,用重氮甲烷酯化,然后通过催化氢解消除保护性苄基或亚苄基。
