A novel unsymmetrical triazolyl-naphthyridinyl-pyridine ligand was designed and synthesized, and employed in the synthesis of a heterogeneous copper complex on reduced graphene oxide. The resulting copper composite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectroscopy (EDX). This
were synthesized from 2‐aminobenzyl alcohols and secondaryalcohols. The effectiveness of this protocol was further extended by successfully synthesizing 2‐alkylaminoquinolines in a one‐pot fashion from amino alcohol, aliphatic nitriles, and alcohols. Gram scale synthesis of various compounds was also investigated to demonstrate the synthetic applicability of this methodology.

An atom-economic and efficient approach to the synthesis of 2-arylquinolines has been developed. The protocol involves an iron-catalysed cascade N-alkylation/aerobic oxidation/Povarov reaction, and the desired quinolines were prepared in moderate to excellent yields from readily accessible anilines, aldehydes, and EtOH/nPrOH, with water as the only side-product. The aniline substrates also act as a
A new phosphine-free Co(II) complex-catalyzed synthesis of various quinoxalines via dehydrogenative coupling of vicinal diols with both o-phenylenediamines and 2-nitroanilines is reported. This complex was also effective for the synthesis of quinolines. The practical aspect of this catalytic system was revealed by the one-pot synthesis of 2-alkylaminoquinolines.
first example of synthesis of pharmaceutically relevant N-heterocycles like substituted quinolines, acridines and 1,8-naphthyridines in water under air usingalcohols in presence of a new water soluble Ir-complex. The viability and efficiency of this approach was demonstrated by the efficient synthesis of biologically active natural product (±)-galipinine and gram scale synthesis of various N-heteroaromatics
