A key clerodane intermediate was prepared during the investigation of the total synthesis of clerocidin. The diterpene backbone was synthesized by an enantioselective Robinson annulation followed by trapping of the enolate using allyl bromide. Selective hydrogenation conditions were developed to introduce the axial methyl group at the C-8 position. A palladium-mediated carbonylation reaction was employed to generate the key alpha,beta-unsaturated dialdehyde. (C) 1998 Elsevier Science Ltd. All rights reserved.
