摘要

The synthesis of aldehyde 11a is reported based upon the intramolecular Diels-Alder reaction of triene 10, the butenolide-diene part of which was obtained in one step via the condensation of the enolate derived from the (Z)-enoate ester 5 with 2-acetoxypropanal. Aldehyde 11a possesses the correct stereochemistry of the tricyclic part of himbacine, an important muscarine receptor antagonist.
