  Acid-induced ring opening of .alpha.-bis(methylthio)methylenealkyl cyclopropyl ketones: a novel route to substituted cyclopentanones through carbocationic cyclizations

  摘要：

  Alpha-[Bis(methylthio)methylene]alkyl 2-styrylcyclopropyl ketones 10a-d,f and their higher enyl analogues 10e,g undergo acid-induced ring opening and carbocationic cyclizations to afford substituted cyclopentanone derivatives. The structures of these products depend on the reaction conditions and the nature of the substituent in the aryl ring. The methodology has been extended to the synthesis of 11-oxosteroid precursors 22 and 25.
