Abstract Described is our effort toward establishing a practical and sustainable synthesis of bis(2‐hydroxy‐3,5‐di‐ t ‐butylphenyl)methanone. In it, we found the phenol‐aldehyde condensation could be efficiently catalyzed by sulfonic acid‐functionalized microporous carbon spheres (MCS‐SO 3 H). Additionally, developed procedures for title ligand applying readily available reagents in lieu toxic chromium trioxide fuming boron tribromide.

The alkylation and heteroarylation of unactivated tertiary, secondary, primary C(sp3)-H bonds was achieved by employing an acridinium photoredox catalyst along with readily available pyridine Noxides as hydrogen atom transfer (HAT) precursors under visible light. Oxygen-centered radicals, generated single-electron oxidation the Noxides, are proposed key intermediates whose reactivity can be easily modified structural adjustments. A broad range aliphatic C-H substrates electron-donating or -withdrawing groups well various olefinic radical acceptors heteroarenes were tolerated.

Abstract We have developed a Visible Light Promoted Catalyst‐Free (VLCF) approach to synthesize novel conjugates of Isoniazid and Maleimide. This method involves the formation an electron donor‐acceptor (EDA) complex between isoniazid maleimide photochemical activity this drives transformation. successfully synthesized Isoniazid‐Maleimide derivatives (3a–d) at gram scale under visible light irradiation without additional photo catalyst chromatographic purification resulting in excellent yields recyclable green solvent. Molecular docking was employed predict silico anti‐tubercular binding modes active site enoyl‐ACP reductase, InhA. The newly compounds exhibited high affinity compared Isoniazid‐NAD adduct, indicating their potential for more effective activity. ADME analysis revealed favourable physicochemical properties, lipophilicity, water solubility, pharmacokinetics, drug‐likeness compound 3a, positioning it as promising candidate further drug discovery development.
