Intramolecular Diels-Alder/Tsuji allylation assembly of the functionalized trans-decalin of salvinorin A.
An enantioselective synthesis of the highly functionalized trans-decalin core (2) of salvinorin A is described. The tetraene 4 was synthesized in six steps from a known L-(+)-tartaric acid derivative. Three contiguous stereocenters, two of them quaternary, on the trans-decalin were established asymmetrically by an intramolecular Diels-Alder/Tsuji allylation sequence.
