  Design, synthesis and biological evaluation of novel non-azole derivatives as potential antifungal agents

  摘要：

  A series of 3-substituted quinazolinones, 2-substituted quinoxalines and 2-substituted benzopyrans were synthesized and evaluated for their antifungal activity in vitro. The new compounds revealed excellent in vitro antifungal activity with broad spectrum. The structure-activity relationships (SARs) of the derivatives were analyzed. Compound 9A2 exhibits better antifungal activity against 5 tested fungi in vitro than fluconazole, especially against Trichophyton rubrum and Microsporum gypseum. This study provides a series of novel lead compounds for the development of non-azole antifungal agents.

  Direct synthesis of N-heterocycles via the acceptorless dehydrogenative coupling is very challenging and scarcely reported under 3d transition-metal catalysis. Here, we have developed an efficient Mn(I)-catalyzed sustainable synthesis of various quinoxalines from 1,2-diaminobenzenes and 1,2-diols via the acceptorless dehydrogenative coupling reaction. Further, this strategy was successfully applied

  通过无受体的脱氢偶联直接合成N-杂环是非常具有挑战性的，在3d过渡金属催化下几乎没有报道。在这里，我们通过无受体脱氢偶联反应，从1,2-二氨基苯和1,2-二醇开发了一种高效的Mn（I）催化可持续合成各种喹喔啉的方法。此外，通过2-氨基苄醇与伯酰胺的反应，该策略成功用于空前的喹唑啉合成。本协议提供了一个原子经济和可持续的途径，通过使用富含地球的锰盐和简单的无膦NNN-三齿配体来合成各种喹喔啉和喹唑啉衍生物。

  Herein, an efficient methodology for the synthesis of a diverse class of N-heterocyclic moieties, such as quinoxalines, benzimidazoles and quinazolines, was developed in water using bio-renewable alcohols. The quinoxalines were successfully synthesized from a wide range of diamines and nitroamines with diols in air. Interestingly, benzimidazoles and quinazolines were synthesized with excellent isolated

  本文中，使用生物可再生醇在水中开发了用于合成多种类别的N-杂环基团例如喹喔啉，苯并咪唑和喹唑啉的有效方法。喹喔啉是由多种二胺和硝基胺与二醇在空气中成功合成的。有趣的是，在不使用任何外部碱的情况下，合成苯并咪唑和喹唑啉具有优异的分离收率。最后，各种N-杂环和药学活性喹喔啉的制备规模合成确立了该方案的实用性。对于这种铱系统，基于动力学和DFT研究提出了金属-配体协同机理。

  A Co‐based heterogeneous catalyst supported on N,P co‐doped porous carbon (Co@NCP) is prepared via a facile in‐situ doping‐carbonization method. The Co@NCP composite features a large surface area, high pore volume, high‐density and strong basic sites. Furthermore, doping of P atoms can regulate the electronic density of Co. Therefore, Co@NCP exhibits good performance for the synthesis of quinoxalines
