The first total synthesis of (+/-)-nimbidiol (1), a biogenetically interesting diterpene isolated from the root bark of Azadirachta indica Linn., has been realized through the diether (8b) prepared by a simple acid-catalyzed cyclialkylation route.

2-Substituted 3,3-dimethylcyclohexan-1-ones are conveniently prepared from the respective 2-substituted 3-methylcyclohex-2-en-1-ones through boron trifluoride-ether-mediated conjugate addition of a methyl group with lithium dimethylcuprate and those incorporating 2β-phenylethyl substituents have been further transformed to podocarpa-8,11,13-triene intermediates in excellent yields.
