In the course of our studies on Cerpegin analogues synthesis, a serendipitous reactivity of enaminolactone nitrile has been observed. Instead of expecting iminocerpegins, we have gained new class of substituted 2-aminopyridines. The methodology has been applied on a wide range of primary amines, as aliphatic, aromatic, heteroaromatic and also, diamines, hydrazines and chiral amines.
在我们对Cerpegin类似物合成的研究过程中,已观察到烯氨基内酯腈的偶然反应性。而不是期待亚氨基cerpegins,我们获得了新的一类取代的2-氨基吡啶。该方法学已被广泛应用于伯胺,如脂族,芳族,杂芳族以及二胺,肼和手性胺。
