Electrochemical carboxylation of lactone enol triflates in DMF containing a catalytic amount of NiBr2·bpy with a platinum cathode and a magnesium anode under an atmospheric pressure of CO2 gave the corresponding cyclic α-alkoxyl-α,β-unsaturated carboxylic acids, captodative cycloalkenes, in good yields.
在含催化量NiBr2·bpy的DMF中,使用铂阴极和镁阳极,在二氧化碳大气压下,通过内酯烯醇三氟甲磺酸酯的电化学羧酸化反应,以良好收率得到了相应的环状α-烷氧基-α,β-不饱和羧酸、俘旋光性环烷类化合物。
