A new method for direct synthesis of β-ketoenamines was developed by a BF3·OEt2-catalyzed cyclization of 1-iodoalkyne and α-keto acid followed by an amine-mediated ring-opening in one pot. Its metal-free conditions allowed the easy synthesis of those products bearing the transition metal-sensitive functional groups. Its three-component process achieved wide range of functionalized products.
通过BF 3 ·OEt 2催化1-碘炔和α-酮酸环化,然后在一个罐中进行胺介导的开环,开发了一种直接合成β-酮烯胺的新方法。它的无金属条件使其易于合成带有过渡金属敏感官能团的产物。其三组分工艺实现了广泛的功能化产品。
