    Abstract: In present report novel thiazines were prepared from starting materials chalcone and thiourea. The resulting compound 6-(4-methoxyphenyl) 4-phenyl-6H-1, 3-thiazin-2-amine (2) was further reacted with ethyl 2-cyano-3, 3-bis (methylthio) acrylate in the presence of catalytic amount of potassium carbonate in DMF under reflux condition that offered nov...

    Abstract: The title compound, (I), has been solved by direct methods and refined to a final R value of 0.038 for 1835 independent reflections. In the structure, the planar [r.m.s deviation = 0.014 Å] chromen-2-one ring and the 7-propionate side chain are inclined to one another at an acute angle of 65.34(9)°. The molecules form R44 (30) tetrameric units via ... Show More
