Abstract
A synthesis of the clerodane insecticide ajugarin-IV and the related clerodane diterpene annonene is described. A Diels-Alder construction of the decalin system is employed for both compounds. In the synthesis of annonene a novel high temperature cleavage and Wolff-Kishner reduction of a cyclic acetal is carried out.Keywords
