Iron-catalyzed C-O bond functionalization of butyrolactam derivatives with various N-/C-nucleophiles

An efficient iron-catalyzed C-O bond functionalization of butyrolactam derivatives with various N-/C-nucleophiles to enable the synthesis of pharmaceutically important butyrolactam derivatives has been developed here. The versatility of the present methodology is demonstrated for direct amination and carbonation by using a variety of sulfonamides, amines, amides, indoles, and 1,3-dicarbonyl compounds under mild conditions. The reaction also showed a wide substrate scope and synthetic simplicity. Additionally, only alcohol was produced as the by-product in all cases. This journal is

Synthesis, characterization and application of nano-N,N,N′,N′-tetramethyl-N-(silica-n-propyl)-N′-sulfo-ethane-1,2-diaminium chloride as a highly efficient catalyst for the preparation of N,N′-alkylidene bisamides

Abstract: A novel mesoporous nanomaterial, namely nano-N,N,N′,N′-tetramethyl-N-(silica-n-propyl)-N′-sulfo-ethane-1,2-diaminium chloride (nano-[TSPSED][Cl]2), was prepared, and characterized using Fourier-transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDS), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), adsorption/desorption porosimetry (BET, Langmuir, BJH and adsorption/desorption isotherm), thermal gravimetric (TG), differential thermal gravimetric (DTG) and X-ray diffraction (XRD) analyses. Afterward, nano-[TSPSED][Cl]2 was used as a highly efficient and recyclable nanocatalyst for the condensation reaction of primary amides (2 eq.) with arylaldehydes (1 eq.) under solvent-free conditions to afford N,N′-alkylidene bisamides in high yields and in short times.

Gold nanoparticles deposited on MnO2 nanorods modified graphene oxide composite: A potential ternary nanocatalyst for efficient synthesis of betti bases and bisamides

The decoration of novel nanostructures such as nano particle and nanorod on the surface of graphene oxide (GO) generate potential heterogeneous nanocatalyst. Highlighting this, in the present work, we have designed a ternary GO-MnO2-Au nanocomposite by decorating MnO2nanorods on the surface of graphene oxide via hydrothermal method, followed by deposition of Au nanoparticles on GO-MnO2 surface. The prepared nanocomposite was thoroughly characterised by different instrumental techniques such as X-Ray diffraction (XRD),Fourier transform infrared spectroscopy (FTIR),Raman spectroscopy, Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), High resolution Transmission electron microscopy (HRTEM), X-Ray photo electron spectroscopy (XPS), N2 adsorption desorption Brunauer–Emmett–Teller (BET) isotherm and Inductively coupled plasma - optical emission spectrometry (ICP-OES). FESEM and TEM images demonstrated that the MnO2 forms rod like structure having diameter of 60–100 nm and are uniformly distributed over the GO surface. HRTEM image clearly signifies gold (Au) nanoparticles having diameter of 7 ± 1.9 nm homogeneously distributed throughout the GO-MnO2 surface. Elementary state of Au and tetravalent nature of Mn as well as reduction of functional group after the decoration was confirmed from XPS studies. The catalyst GO-MnO2-Au was found to be the superior catalyst for synthesis of biologically active molecules such as Betti bases and Bisamides. The high catalytic activity of the materials can be attributed to the small and homogeneous distribution of gold nanoparticles, high redox potential of rod shaped MnO2 and the synergistic effect between GO, MnO2 and Au. All the reaction conditions were optimised by varying catalyst dosage, effect of solvent and temperature. The GO-MnO2-Au was easily recycled with minimal leaching and the product yield was found to be 85–90% after 4th cycle demonstrating the stability and durability of our nanocomposite.

N,N,N′,N′-tetramethylethylene-diaminium-N,N′-disulfonic acid trifluoroacetate and pyridinium-N-sulfonic acid hydrogen sulfate as highly effective dual-functional catalysts for the preparation of N,N′-alkylidene bisamides

In this research, Br?nsted-acidic ionic liquids N,N,N′,N′-tetramethylethylene-diaminium-N,N′-disulfonic acid trifluoroacetate ([TMEDSA][TFA]2) and pyridinium-N-sulfonic acid hydrogen sulfate ([Py-SO3H][HSO4]) have been introduced as dual-functional catalysts for the green, simple and effective preparation of N,N′-alkylidene bisamides by the reaction of primary amides (2 eq.) with arylaldehydes (1 eq.) under solvent-free conditions. The reaction results and conditions of the catalysts have been compared with the previously reported ones. [TMEDSA][TFA]2 and [Py-SO3H][HSO4] were superior to the previously reported catalysts in terms of two or more of these factors: Reaction times (10-45 min), yields (86-98%), temperature and the reaction conditions. Additionally, a plausible and attractive mechanism based on dual functionality of the catalysts has been proposed.
