Numerous methodologies to obtain pyridines from ylidenemalononitriles are described in the literature. Nevertheless, they are limited to the use of microwave or conventional heat and few lead to 2,3,4 or 2,3,4,5-substituted pyridines as multi-proposal molecular scaffolds or even universal pyridines. Herein, we present a mild and facile solvent-free methodology to obtain a scope of multi-substituted
文献中描述了许多从亚基丙二腈获得吡啶的方法。然而,它们仅限于微波或常规加热的使用,并且很少导致2,3,4或2,3,4,5-取代的吡啶作为多方案分子支架甚至通用吡啶。在此,我们提出了一种温和且简便的无溶剂方法,可在室温下获得一系列多取代吡啶。我们还报告了一个例子,其中所得的氨基烟腈之一表现出聚集诱导发射(AIE)的初步证据。
