An efficient palladium/copper-catalyzed approach to the synthesis of highly substituted 3-formyl furans from the reactions of readily available α-bromoenaminones with terminal alkynes has been developed. This methodology was realized by the cascade reactions of Sonogashira coupling and the subsequent intramolecular cyclization.
已经开发了一种有效的钯/铜催化方法,该方法可通过容易获得的α-溴烯胺与末端炔烃的反应合成高度取代的3-甲酰基呋喃。该方法是通过Sonogashira偶联的级联反应和随后的分子内环化实现的。
