The diastereoselectivities in the acid-mediated cyclization of (E)- and (Z)-5,6-dimethyl-8-trimethylsilyl-6-octenals, both stereoselectively synthesized, were investigated. Excellent preference for the formation ofcis-dimethylcyclohexanols was realized, specially in the case of the (Z)-substrate where they formed exclusively. The selectivity in the hydroxyl group configuration varied in relation with
