Methylation of the α,β-unsaturated ketone (2) in presence of lithium di-isopropylamide and hexamethylphosphoramide complex yielded the methylated ketone (3). Reduction of ketone (3) with sodium borohydride yielded the alcohol (4) whose tosyl derivative (5) on heating with dimethylformamide and lithium bromide afforded the diene (18). Oxidation of (18) with chromic acid produced the dienone (19) and
