An efficient preparation of α,α-dimethoxyalkanoates (2) has been performed by electrolytic desulfurization of α-(2-benzothiazolylthio) alkanoates (1) in MeOH containing CuCl2 as a catalytic additive, yielding 2 (94–57%) together with disulfide 3 (88–48%).
通过在含有 CuCl2 作为催化剂的 MeOH 中对α-(2-
苯并噻唑基
硫基) 烷酸酯 (1) 进行电解脱
硫,高效制备了 α,α-二甲氧基烷酸酯 (2),得到了 2 (94-57%) 和二
硫化物 3 (88-48%)。
