Abstract

The appropriate choice of dimethylsulfonium methylide generation conditions enables the highly regioselective tandem ylide addition-eliminative olefination to 1,3-dienedioates providing 1,3-butadien-2-ylmalonates, a novel class of 2-substituted 1,3-dienes suitable for quick assembly of precursors for type 2 intramolecular Diels-Alder reactions.
