A base-promoted one-pot tandem reaction has been developed from 3-(1-alkynyl)chromones with various acetonitriles to afford functionalized amino-substituted xanthones 3 under microwave irradiation. This tandem process involves multiple reactions, such as Michael addition/cyclization/1,2-addition, without a transition metal catalyst. This method provides an efficient approach to build up natural product-like
由3-(1-炔基)色酮与各种乙腈开发了碱促进的一锅串联反应,以在微波辐射下提供官能化的氨基取代的氧杂蒽3。该串联过程涉及多个反应,例如迈克尔加成/环化/ 1,2-加成,而没有过渡金属催化剂。该方法提供了一种有效的方法来快速建立类似天然产物的多样化的氨基取代的蒽酮骨架。
