high-yielding, and highly diastereoselective three-component coupling reaction of O,O-diethyl hydrogen phosphorodithioate, aromatic aldehydes, and activated olefins. The synthesis involves Michael addition of the dithioate to acrylonitrile/methyl acrylate followed by addition of the resulting carbanion to an aldehyde and intramolecular cyclization to afford 2-arylthietane-3-carbonitriles/carboxylates at room
