A novel, facile, and efficient Lewis-acid-catalyzed [4 + 1] annulation protocol for the construction of functionalized polycyclic-fused furans is developed. This methodology is free of transition metals and ligands and provides a rapid synthetic route to divergently orientated polycyclic furans in good yields. In addition, this protocol can also be used to synthesize multisubstituted furans.
开发了一种用于构建功能化多环稠合呋喃的新型、简便且高效的路易斯酸催化 [4 + 1] 环化方案。该方法不含过渡金属和配体,并提供了一种快速合成途径,以良好的收率获得发散取向的多环呋喃。此外,该协议还可用于合成多取代呋喃。
