An efficient transition-metal-free photoinduced intracyclization of 4H-chromen-4-ones in EtOH-HO (7:1, v/v) at ambient temperature for the construction of complicated fused-ring heteroaromatics is established. The reaction proceeds smoothly without requiring any catalysts/additives.
在室温下，在 EtOH-HO（7:1，v/v）中建立了一种高效的无过渡金属光诱导 4H-色烯-4-ones 的内环化反应，用于构建复杂的稠合环杂芳烃。该反应无需任何催化剂/添加剂即可顺利进行。
