Polyene cyclization of the titled compounds under catalysis with AICI 3/SnCI 4 gave rise to the corresponding polycycllc products, many of which were structurally highly unexpected, and thus, Individual X-ray analysis was required to finalize the structural Identification. Mechanistically, an unusual 1,2-hydride shift is proposed to elucidate the product formation.
