摘要：

Low-energy light, endowing with excellent characteristics of lower energy, fewer side reactions, more abundance in solar light. The scenario has been developed for the fabrication of indenone through a low-energy green light driven radical annulation reaction between alpha-keto acids and internal alkynes using Rhodamine 6G as photocatalyst. Various kinds of substrates are suitable for this methodology, affording the corresponding indenones in a greener and efficient manner. An efficient photocatalysis has been developed for the synthesis of indanone using low-energy green light as input energy. This methodology provides a greener avenue to construct indanone through a metal-free photocatalytic radical annulation reaction between alpha-keto acid and internal alkyne. image
