“…The use of a pyridine N -oxide ligand was presumably inspired by prior studies that utilized pyridine N -oxide ligands for general N -arylation [ 133 , 134 , 135 ]. The pyridine-based ligand L2 , which contains an iminopyridyl moiety, was used for the N -arylation of indoles in DMSO at 120 °C ( Table 6 , entry 2) [ 136 ]. Another ligand L3 that contains an iminopyridyl moiety in its molecule was reported in 2021 ( Table 6 , entry 3) [ 137 ].…”

This review summarizes the current state-of-the-art procedures in terms of the preparation of N-arylindoles. After a short introduction, the transition-metal-free procedures available for the N-arylation of indoles are briefly discussed. Then, the nickel-catalyzed and palladium-catalyzed N-arylation of indoles are both discussed. In the next section, copper-catalyzed procedures for the N-arylation of indoles are described. The final section focuses on recent findings in the field of biologically active N-arylindoles.

The straightforward combination of commercial picolinaldehyde and 2-aminopyridine led to the preparation of N ,1di(pyridin-2-yl)methanimine ligand HL 1 . Under aerobic conditions, HL 1 self-assembles with manganese (Mn) ions to afford two high-spin mononuclear Mn(III) complexes of general formula [MnL 2 2 ] + Cl (1) and [MnL 2 2 ] + (NO 3 ) (2). Their synthesis is mediated via (in situ) ligand transformation and oxidation of initial Mn(II) ions. Such unexpected reorganization contributes in the stabilization of the complexes. The mononuclear compounds 1 and 2 display unusual Jahn-Teller distortion along the z-axis, as evidenced by single-crystal X-ray diffraction and do exhibit an S = 2 ground spin state.

“…[15,16] Recently synthesis and characterization of new biologically active Pyrrolo [2,3-b]Pyridine scaffolds were also reported by Farid M Sroor. [17] Several base catalysed reactions are reported in the literature for various important organic transformations i. e. Hunig's base; [18] silver carbonate; [19] DABCO [20] and cesium carbonate as a base. [21]…”

cesium carbonate mediated synthesis of desired 1 N-substituted phenylethanone analogue of 4-azaindole is carried out in Dimethylformamide. Further formation of derivatives of 6 is produced from desired analogue of 4-azaindole. The mechanistic pathway is analyzed with density functional theory calculations which supported the experimental results. Due to structural similarity of azaindole core nucleus with purine ring of ATP, it is a promising /attractive molecule to be explored for its biological potential.
