And aryne makes three: The three‐component coupling of arynes, DMF, and active methylenes has provided an efficient method for the synthesis of 2H‐chromene and coumarin derivatives (see scheme). The sequential multistep reactions are driven by the release of strain energy in the arynes and intermediates, and this finding was supported by thermodynamics.
芳烃可以做到三点:芳烃,DMF和活性亚甲基的三组分偶联为2 H-色烯和香豆素衍生物的合成提供了一种有效的方法(参见方案)。顺序多步反应是由芳烃和中间体中应变能的释放驱动的,这一发现得到了热力学的支持。
