Hydrogenolysis of 2-bromo-2-deoxyaldono-1,4-lactones in ethanol solution with palladium as catalyst gives good yields of the corresponding 2,3-dideoxylactones with removal of not only the bromine atom but also the C-3 hydroxy group.
在用
钯作为催化剂的条件下,2-
溴-2-脱氧醛糖-1,4-内酯在
乙醇溶液中进行氢解反应,可以得到高产率的相应2,3-脱氧内酯,同时去除了
溴原子及C-3羟基。
