A convenient electro-catalyzed multicomponent synthesis of 4: H -thiopyran derivatives

An environmentally benign synthesis of substituted 4H-thiopyrans was carried out by the condensation of aromatic aldehydes, malononitrile, carbon disulfide and primary amines. Constant potential electro synthesis was carried out in an undivided cell at ro

MWI-promoted preparation of 4H-thiopyran derivatives through one-pot multi-component reactions

One-pot reaction of aromatic aldehydes, cyanothioacetamide and malononitrile under microwave irradiation proved to be an efficient way for the synthesis of 2,6-diamino-4-aryl-4H-thiopyran-3,5-dicarbonitriles without any added catalyst.
