ABSTRACT New classes of 3N-substituted-2-[(3-methyl-1H-pyrazole-5-yl)-imino]-5,6-diphenyl-2H-1,3-thiazin-4(3H)-ones have been synthesized, via one pot reactions between pyrazolylthioureas, 2,3-diphenylcyclopropenone and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone. The structures of the products have been confirmed by different spectroscopic analyses. A… Click to show full abstract
ABSTRACT New classes of 3N-substituted-2-[(3-methyl-1H-pyrazole-5-yl)-imino]-5,6-diphenyl-2H-1,3-thiazin-4(3H)-ones have been synthesized, via one pot reactions between pyrazolylthioureas, 2,3-diphenylcyclopropenone and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone. The structures of the products have been confirmed by different spectroscopic analyses. A rationale for the formation of the products is presented. GRAPHICAL ABSTRACT
