Selective formation of substituted cyclopentane derivatives from hexa-1,5-dienes via oxidative cyclization in the presence of Pd(OAc)2–MnO2–benzoquinone as catalyst
Abstract
Hexa-1,5-dienes undergo oxidative ring closure catalysed by palladium acetate using p-benzoquinone–manganese dioxide as oxidant to give acetoxy-substituted methylene-cyclopentane derivatives.
