                                    Synthesis of α-ambrinol was successfully accomplished by cyclization of dihydro-γ-ionone ethylene acetal which was prepared by the titanium(IV)-promoted reaction of 3,3-dimethyl-1-trimethylsiloxycyclohexene with methyl vinyl ketone ethylene acetal followed by exo-methylenation with triphenylphosphonium methylide.
