A simple and efficient synthesis of heterocycle-fused 2H-thiopyrans, furo-, benzofuro-, thieno-, benzothieno-, pyrrolo- and indolo-2H-thiopyrans, from heteroaromatic thioketones and α-chloroacrylonitrile or α-bromoacrylic esters via a hetero Diels-Alder r

An efficient and convenient procedure is described for the synthesis of heterocycle-fused 2H-thiopyrans having ortho-dimethylene structures via a hetero Diels-Alder reaction-dehydrohalogenation process starting from heteroaromatic thioketones and α-chloro
