A facile one-pot synthesis of 2-(pyrrolyl)-4-aryl(hetaryl)-5-cyano-6-methylpyridines in 63–87% yield via the cyclization of available acylethynylpyrroles with two molecules of acetonitrile under the action of lithium metal at room temperature has been developed.
一种简便的一锅法合成2-(吡咯基)-4-芳基(杂环基)-5-氰基-6-甲基吡啶,收率为63-87%。该方法通过在室温下使用锂金属催化剂,将可用的酰乙炔基吡咯与两分子乙腈环化反应而得。
