SYNTHESIS OF (+/-)-VITRENAL

(+/-)-Vitrenal (1), a sesquiterpene aldehyde with a novel vitrane skeleton, was synthesized from a monoterpene piperitenone (2) by 12-step reactions in ca. 7percent overall yield. 2-Formylisocarane, derived from 2 via (+/-)-isocaran-2-one was allylated stereospecifically and, after protection of the formyl group, the allyl chain was modified to a 4-methoxy-3-butenyl group.Acid treatment of the masked dialdehydic intermediate yielded 1 by concomitant deprotection and aldol condensation.
