cyclizations of optically active allylsilanes bearing electrophilic functional groups on their a-alkyl side chains were examined. The allylsilanes having aldehyde and enone functional groups underwent the intramolecular cyclizations in the presence of Lewis acid catalysts to give 6and 7-membered cycloalkenes with high stereoselectivity in good yields. Reactions of the allylsilanes having a-hydroxyalkyl chain
