Pd/Cu catalyzed oxidative dual C-H bond activation/carbonylation still remains a great challenge due to the generation of by-products via C-C bond formation. Herein we developed a straightforward Pd/Cu-catalyzed oxidative dual C-H bond carbonylation process to access biologically and pharmaceutically important fluorazones from easily available N-aryl pyrroles and CO. A wide range of functional groups were well tolerated in this transformation, and O2 could be utilized as the only terminal oxidant to promote the oxidative carbonylation process.

Novel pyrrolyl hydrazones and their copper complexes have been synthesized and characterized using analytical and spectral techniques to show the tetrahedral geometry for Cu(II) complexes. Biological activities of hydrazones have been assessed to understand the role of metal ion on their biological activity and the effect of pyrrolyl hydrazones. In?vitro antitubercular activity against Mycobacterium tuberculosis of the metal complexes (13b and 13r) exhibited the highest antitubercular activity that are quite close to rifampicin (0.4?μg/mL), giving a MIC of 0.8?μg/mL. All other compounds showed good activity with the MIC values ranging from 1.6 to 100?μg/mL. A comparative study of inhibition values of the ligands and their complexes showed higher antimicrobial activity of the complexes than the ligands. Some compounds have a good activity against InhA and in particular, compounds 12r, 13b and 13r exhibited more than 60% binding with the enzyme even at 5?μM (exhibited good IC50 upto 2.4?μM). Most of the active molecules have a very less cytotoxicity against the human lung cancer cell-line A549. The docking and 3D-QSAR studies have been carried out to provide some insights into the mechanism of action for this class of compounds.
