Synthesis of 2-sulfanylidene-1,3-thiazolidin-4-one derivatives
摘要:
Three-component condensation of primary amines with carbon disulfide and dialkyl maleates afforded the corresponding alkyl (3-R-4-oxo-2-sulfanylidene-1,3-thiazolidin-5-yl)acetates whose structure was confirmed by independent synthesis and IR and H-1 NMR spectroscopy.
Compounds of the type π-C5H5NiPBu3SC(S)X (X = R, OR and NRH) are obtained from reactions between [π-C5H5Ni(PBu3)2]+Cl− and SC(S)X− in aqueous solution. Compounds such as π-C5H5NiPBu3SC(S)NRH are also obtained by reactions of π-C5H5NiPBu3SH with RNCS.

synthesized compounds were screened for their antitubercular, anti-HIV and antibacterial activity against different gram positive and gram negative strains by agar dilution method. Among the test compounds, 2-(3-(4-chlorophenyl)-4-oxo-3,4-dihydroquinazolin-2-yl)-2,3-dihydrophthalazine-1,4-dione (QCT7) shown most potent antibacterial activity against E. coli , and S. aureus with the MIC of 3 µg/mL. The compound
