摘要

以2h -吡啶与水合肼为原料，在甲醇-乙醇溶剂中合成了二氢吡啶核心衍生物，收率为70 - 90%。在打开内酯环的回流条件下，以优异的收率生产单芳基吡啶-2- 1衍生物3a-d。该方法的主要优点是反应时间短，胺的利用率高，收率大大提高。苦味酸可以通过电子转移或能量转移机制显著地淬灭分子3d的发射，使其能够作为爆炸物硝基化合物检测的化学传感器。

Design, synthesis, and photophysical characterization of monoaryl-pyridine-2-ones derivatives: Exploring aggregation-caused quenching vs aggregation-induced emission

The dihydropyridine core derivatives have been synthesized from the reaction of 2H-pyrone with hydrazine hydrate, in methanol ethanol solvent, obtained 70–90 %. Under the reflux condition occurred withopening of the lactone ring to yield monoaryl-pyridine-2-ones derivatives 3a-d in excellent yields. This method's main advantages are short reaction time, high amine utilization, and considerably improved yield. The emission of the molecules 3d can be significantly quenched by picric acid through electron transfer or energy transfer mechanisms, enabling them to function as chemosensors for explosive nitroaryl compound detection.

期刊介绍： Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry. Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters. Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
