✦ Synopsis
Electrochemical reduction of alicydic vinyl triflates (la -1 e) in a DMF solution containing 0.1 M Be4NIF 4 under an atmospheric pressure of cmbon dioxide with a platinum cathode and a magnesium anode resulted in the cleavage of an oxygen-sulfer bond of 1 to give the corresponding 15-keto cmboxylic acids (2n-2e) in yields of 28-77%.
