Regioselective Synthesis of
2-(Arylthio)benzoates by the First Catalytic [3+3] Cyclocondensations
of 3-(Arylthio)-1-(trimethylsilyloxy)-1,3-butadienes with 1,1,3,3-Tetramethoxypropane
2-(Arylthio)benzoates were regioselectively prepared by the first catalytic [3+3] cyclizations of 3-(arylthio)-1-(trimethylsilyloxy)-1,3-butadienes with 1,1,3,3-tetramethoxypropane.
