A novel oxidative ring-opening of 2-substituted furans into methyl 4-substituted (E)-4,4-dimethoxy-2-butenoates has been performed by electrolysis in an NH4Br–Et4NClO4–MeOH–(Ptelectrodes) system.
通过在 NH4Br-Et4NClO4-MeOH- (Ptelectrodes) 系统中进行电解,将 2-取代的
呋喃氧化开环成 4-取代的 (E)-4,4-dimethoxy-2-butenoates 甲酯,这是一种新颖的氧化开环方法。
