Electrophile-Initiated Lactonization of 7-Phenytricyclo[4.1.0.02,7]heptane-1-carboxylic Acid
摘要:
Treatment of 7-phenyltricyclo[4.1.0.0(2,7)]heptane-1-carboxylic acid with benzenesulfenyl chloride, mercury acetate, and hydrogen chloride leads to cleavage of the central C-C bond in the bicyclobutane fragment and heterocyclization to substituted bicyclo[3.1.1]heptane-6,7-carbolactones.
