Abstract: | An efficient synthesis of 6H-6-iminothiopyran-2,3-dicarboxylate and 1H-isothiochromene-3,4-dicarboxylate derivatives via one-pot reactions between acetylenic esters, aryl isothiocyanates and enaminones in dichloromethane at room temperature is described. The mild reaction condition, high yields and the new products are advantages of our method. |
