Abstract

3-Aryl-1-[(E)-cyanomethylidene]-1H-pyrido[2,1-b]benzothiazole-4-carbonitriles (3) and the polysubstituted pyrido[2,1-b]benzothiazoles (8, 9) have been prepared from the reaction of 2-benzothiazoleacetonitrile (2) with 6-aryl-4-methylsulfanyl-2-oxo-2H-pyran-3-carbonitrile (1) and the ketenedithioacetals (6, 7), respectively.
