Electron-deficient alkenes undergo organocatalysed formal [3+2]-cycloaddition with isatin-derived imines, generating complex spirocyclic products high yield and stereoselectivity.

Three copper(II) complexes of salicylaldehyde N(4)-phenyl thiosemicarbazone (H2L ) and two copper(II) complexes of N(4)-cyclohexyl thiosemicarbazone (H2L ) have been synthesized and characterized by different physicochemical techniques like magnetic studies and electronic, infrared and EPR spectral studies. The complexes 1⁄2ðCuL1Þ2 12H2O ð1Þ and [(CuL )2] (4) having dimeric structure. The thios...

Isatin, N-methyl isatin and N-benzylisatin were smoothly monobrominated in the 5-position by treatment with pyridinium bromochromate (PBC) in acetic acid medium. In the similar conditions indigo underwent bromination and oxidation to give 5-bromoisatin in high yield.

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

Evaluation the Effect of Chemotherapy Drugs and Thiosemicarbazone Complexes on Expression URHC CASC15 LncRNAs in Acute Lymphoblastic Leukemia Cell Line

Anticancer drugs A series of monoand dinuclear (η-arene) ruthenium(II) complexes were prepared by reaction of thiosemicarbazone ligands derived from benzaldehyde and ruthenium(II) precursors of the general formula [Ru(η-arene)(μ-Cl)Cl]2, where arene=p-PrC6H4Me or C6H5C3H6COOH. These complexes were characterized by NMR and IR spectroscopy, ESI-mass spectrometry and elemental analysis. The molecu...
