A mild and efficient one-pot visible light irradiated synthesis of 2-aminobenzothiazole 4(a–l) from arylisothiocyanate 1(a–l) and secondary amines 2 have been reported in presence of eosin Y as an organophotoredox catalyst at room temperature under aerobic condition. This synthesis includes application of air and visible light as inexpensive, readily available, high atom economy, non-toxic and ...

(1,4,5-Triphenylimidazol-2-yl-thio)butyric acid hydrazide (3) was obtained via alkylation of 1,4,5-triphenylimidazol-2- thiol (1) with ethylbromobutyrate, followed by addition of hydrazine hydrate. Treatment of acid hydrazide 3 with carbon disulfide in an ethanolic potassium hydroxide solution gave the intermediate potassium dithiocarbazinate salt, which was cyclized to 4-amino-5-[(1,4,5-triphe...

OBJECTIVE(S) Inhibitors of p38 MAP kinase are considered as suitable target in the treatment of inflammatory diseases such as rheumatoid arthritis and bowel inflammatory diseases. The development of 5-alkylthio-1-aryl-2-(4-pyridinyl) triazoles as inhibitors of p38 MAP kinase is described. These are analogues of 4- pyridinyl imidazole p38 MAP kinase inhibitor reported by Merck Research Laborator...

An efficient synthesis of 2H-thiopyran-3,4-dicarboxylate derivatives via one-pot reactions between acetylenic esters, arylisothiocyanates and enaminones in water is described.The advantages of this work were: (1) the reaction was performed under neutral and more important in water as the solvent. (2) No catalyst was required for this reaction. (3) The simplicity of the present procedure made it...
