摘要：

Isothiazolothienopyridines have been prepared by a domino reaction (the S(N)2 reaction -> the Thorpe-Ziegler reaction -> the Thorpe-Guareschi reaction type) from disodium 4-cyanoisothiazole-3,5-dithiolate. By changing the order of addition of the alkylation reagents in the reaction with disodium 4-cyanoisothiazole-3,5-dithiolate both possible isomers of the isothiazolothienopyridines are synthesized. These isomers were further used in three-component domino reaction (the Knoevenagel reaction -> the Michael reaction -> the hetero-Thorpe-Ziegler reaction type) to obtain wide range of isomeric isothiazolothienopyranopyridines.
