The cationic cyclization of the carbinol 3a(Z) occurred stereoselectively and resulted in a mixture of the hydrindane 4a and the octalin 5a, both with trans-configuration of side chain and angular methyl group.Cyclization of 3b(E) yielded in 4b and 5b, both with cis-configuration.The structure of 4a,5a was proved by transformation to the diketones 8,9.
