  Iodine‐promoted facile protocol is designed for the production of pyridines at room temperature under ultrasound irradiation. Eleven pyridine derivatives in excellent yields (91–97%) are synthesized with 2 hr reaction time. Additional advantage of the proposed ultrasound‐assisted eco‐friendly, cost‐effective protocol is easy separation of product, and our in silico studies show good binding affinity

  碘促进的操作规程旨在用于在室温下超声辐射下生产吡啶。在2小时的反应时间内可以合成11种吡啶衍生物，产率很高（91–97％）。拟议的超声辅助的生态友好，经济高效的方案的另一个优势是易于分离产品，我们的计算机研究表明对结合具有良好的结合亲和力，并具有很强的氢相互作用。

  An efficient and promising synthetic approach to assemble skeletons of multifunctionalized pyridine derivatives in presence of recyclable heterogeneous sulfated tin oxide (STO) catalyst has been evolved. The STO catalyst was used as a promoter for the cyclocondensation process in ethanol at 70°C. Overall performance of this catalyst was attributed to the cooperative contribution of its Lewis and Brønsted‐Lowry

  已经开发出一种有效且有前途的合成方法，用于在可回收的异质硫酸盐氧化锡（STO）催化剂存在下组装多官能吡啶衍生物的骨架。将STO催化剂用作70°C乙醇中环缩过程的促进剂。该催化剂的整体性能归因于其Lewis和BrønSTed-Lowry酸性位点的协同作用。纳米STO催化剂是通过溶胶-凝胶法合成的，并通过傅里叶变换红外（FTIR）光谱，X射线衍射（XRD），1表征H-NMR和扫描电子显微镜（SEM）。该催化剂可耐受大多数底物，实验方案显示出宝贵的能力，包括高收率，操作简便，反应时间短和环境友好。新合成的非均相催化剂易于分离和重复使用。所有反应均在随后的循环中进行，而催化活性没有明显损失，并且熟练度很高。
• An efficient method for the multicomponent synthesis of multisubstituted pyridines, a rapid procedure using Au/MgO as the catalyst

  Au/MgO proved to be a highly efficient and reusable catalyst for multicomponent coupling reactions at 70 degrees C. The synthesized multisubstituted pyridines were obtained in high yields and in short reaction times. With facile work-up, the novel catalyst can be readily recovered after the reaction and reused without any loss of its catalytic activity. (C) 2014 Elsevier Ltd. All rights reserved.
