Abstract
The cyclopropyl carbinols 8 and 9 obtained by either borohydride reduc tion (or Grignard addition) of the cyclopropyl ketones 1 are shown to undergo acid induced ring opening and intramolecular cyclization (5-ex o or 6-endo) or deprotonation to afford either cyclopentene, biphenyl or conjugated polyene derivatives depending on the nature of Lewis aci d, reaction conditions and the structural features present in the cycl opropyl carbinol. A probable mechanism for the formation of various pr oducts has been suggested.
