  • Nebivolol nanoparticles: a first catalytic use in Biginelli and Biginelli-like reactions
    作者:Anamika Khaskel、Pranjit Barman、Subir Kumar Maiti、Utpal Jana

    Herein, we report the catalytic activity of nebivolol nanoparticles a novel organocatalyst for the synthesis of DHPMs and DHPM-5-carboxamides. The nanoparticles are confirmed by DSC, TEM, AFM, and IR spectroscopy. The catalyst can be readily recovered and reused for the next four runs without any significant impact on the yields of the products. The products are fully characterized by FTIR, 1H NMR, 13C NMR, and distortionless enhanced polarization transfer (DEPT) NMR. The methodology adopted here offers several advantages such as solvent-free reaction, low loading of catalyst, short reaction times, and quantifiable yields.

    An air‐stable complex of zirconium (IV)‐salophen perfluorooctanesulfonate (1) was successfully synthesized by reacting Zr (salphen)Cl2 and C8F17SO3Ag. Complex 1 was characterized and studied by different techniques (NMR, IR, HRMS, TG‐DSC, conductivity and acidity measurements), and was found to be air‐stable, water tolerant, thermally stable and strongly Lewis‐acidic. Complex 1 exhibited high catalytic

    An innovative route for the construction of 2-oxo and thioxo-1,2,3,4-tetrahydropyrimidines was delineated through a multicomponent reaction under Biginelli conditions, starting from different aromatic aldehydes, ?-ketoesters and urea or thiourea. Proper choice of copper complex (PhNH3)2CuCl4, as a novel homogeneous catalyst, enables facile, efficient, and inexpensive reaction under mild experimental conditions. Moreover, we present the first application of this complex salts in organic synthesis ever. The obtained products are of high purity, and can be easily isolated from the reaction mixture in good to excellent yields. Also, compared to the classical Biginelli reaction conditions, the present method has the advantages in higher yields and experimental and work-up simplicity. To illustrate the joint catalytic action of the Cu2+ and phenylammonium ions, two key steps of Biginelli reaction were examined using the M06 functional.
