A series of dihydropyridin containing thiazolinone derivatives (4a–4r) have been designed, synthesized and their biological activities were also evaluated as potential EGFR and HER-2 kinase inhibitors and tumor cell antiproliferation.

Room-Temperature Synthesis of Tetrasubstituted 1,3-Dithioles by Dimerizing Sulfuration of Chalcones with Elemental Sulfur
Chalcones were found to undergo sulfurative dimerization with elementalsulfur to tetrasubstituted 1,3-dithioles. The reaction was found to proceed at room temperature in the presence of a nitrogen-base catalyst in DMSO.
