The reaction of acetylenic ketones with cyanothioacetamide in the presence of morpholine yields 4,6-disubstituted 2-thioxo-1,2-dihydropyridine-3-carbonitriles. Structure of the obtained compounds was proved using 2D NMR spectroscopy, as well as transformations into 3-aminothieno[2,3-b]pyridine-2-carboxamide derivatives.
在吗啉存在下,乙炔酮与氰基硫代乙酰胺的反应产生4,6-二取代的2-硫代-1,2-二氢吡啶-3-甲腈。使用2D NMR光谱法以及转化成3-氨基噻吩并[2,3 - b ]吡啶-2-甲酰胺衍生物证明了所获得化合物的结构。
