(-)-Prezizanol (-)-1, (-)-prezizaene (-)-2, isolated from Diels, and their epimers, 5 and 6, were synthesized employing β-keto ester 7, readily available from ()-(+)-pulegone, as a starting material. -Epimers, 5 and 6 were obtained with over 95 % stereoselectivity reductive methylation of enone 22. The natural isomers, (-)-1 and (-)-2, were synthesized hydroxy-directed hydrogenation of the corresponding allylic
