摘要

Abstract 3-(2-Amino-5-methylpyridin-3-yl)-1-arylprop-2-yn-1-ones 2, readily available through Pd-catalyzed carbonylative coupling of 5-methyl-3-[2-(trimethylsilyl) ethynyl] pyridine-2-ylamine (1) with aryl iodides in the presence of carbon monoxide, undergo a domino conjugate addition/annulation reaction to give 4-heterosubstituted 2-aryl [1, 8] naphthyridines 3 in high yields.
