The first stereoselective totalsynthesis of the bibenzyl tetrahydrocannabinol, (-)-perrottetinene, has been achieved from readily available starting materials. The absolute stereochemistry is derived from a chiral gamma-hydroxy vinylstannane. The key reaction is the synthesis of the cis-disubstituted cyclohexene ring of perrottetinene by diastereoselective Ireland-Claisen rearrangement and a ring-closing
