    Design, synthesis, docking study and biological evaluation of some novel tetrahydrochromeno [3′,4′:5,6]pyrano[2,3-b]quinolin-6(7H)-one derivatives against acetyl- and butyrylcholinesterase
    摘要:
    Novel hybrid derivatives of two known scaffolds; tetrahydroaminoquinoline and coumarin were synthesized and evaluated for both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities. By means of an efficient nanocatalyst, the reaction time for the syntheses of the target compounds was reduced. Subsequently, Ellman's modified method was used to evaluate the enzyme inhibitory activity of the synthesized structures. It was observed that most hybrid structures were moderate to potent inhibitors of AChE compared to Tacrine as the reference drug among which 7f with 4-fluorophenyl substituent was the most active compound (IC50 = 5 nM).

  • Heterogeneous ditopic ZnFe<sub>2</sub>O<sub>4</sub>catalyzed synthesis of 4H-pyrans: further conversion to 1,4-DHPs and report of functional group interconversion from amide to ester
    作者:Paramita Das、Arghya Dutta、Asim Bhaumik、Chhanda Mukhopadhyay

    日期:——
    Highly stable, environmentally benign ZnFe2O4 nanopowder was prepared, characterized and applied in the one-pot, three-component synthesis of 4H-pyrans in water. The ZnFe2O4 catalyst provides both acidic (Fe3+) and basic functionalities (O2−) as the reaction requires. The advantages of this method lie in its simplicity, cost effectiveness, environmental friendliness and easier scaling up for large scale synthesis. Water was exploited both as a reaction medium as well as a medium for synthesis of the catalyst. Moreover, water was the only byproduct. The present report puts forward an application of 4H-pyrans for the synthesis of 1,4-DHPs. This is the first attempt towards the synthesis of 4H-pyran-3-carboxylate from 4H-pyran-3-carboxamide. The corresponding functional group interconversion from amide to ester is rare in organic synthesis.
    成功制备、表征并应用了一种稳定且对环境友好的ZnFe2O4纳米粉,在水相中实现了4H-吡喃的一锅法三组分合成。ZnFe2O4催化剂同时提供了反应所需的酸性(Fe3+)和碱性(O2−)功能。该方法的优势在于其简单性、成本效益、环境友好性以及更易于放大进行大规模合成。水既被用作反应介质,也被用作催化剂的合成介质。此外,水是唯一的副产品。本报告提出了一种应用4H-吡喃合成1,4-二氢吡啶(1,4-DHPs)的方法。这是首次尝试从4H-吡喃-3-甲酰胺合成4H-吡喃-3-羧酸酯。在有机合成中,从酰胺到酯的功能团转换是罕见的。

    product switches from pyrimidine to enol lactones and δ‐keto acids inside the nanoreactor. The shape/size selectivity in the liquid phase is a highly desired phenomenon in organic synthesis. We prepared four different varieties of porous silica materials to obtain this product selectivity. Very high yields of these biologically relevant compounds surpass that achieved by existing methodologies. Again
