Abstract
(Equation presented) A formal total synthesis of the selective muscarinic receptor antagonist himbacine is presented. Key C-C bond-forming steps include an intramolecular Diels-Alder reaction, Stille coupling reactions, and a 6-exo-trig acyl radical cyclization to a conjugated enyne. An unexpected secondary alcohol to chloride conversion is witnessed during attempted thionocarbonate formation.
