The invention discloses a method for performing C(sp3)-H functionalization cyclization reaction under a photooxidation reduction catalytic system. Under the photooxidation reduction catalytic system,aryl sulfonyl chloride as shown in a formula III which serves as a free radical donor and a 2-alkyl-2-propargyl malonate compound as shown in a formula II are subjected to oxidation quenching circulation mechanism to synthesize a series of five-memberred ring compounds as shown in a formula I. (The formulas are as shown in the description).
Description
technical field [0001] The application belongs to the field of organic synthesis, and specifically relates to a C(sp3)-H functional group cyclization reaction method under a photoredox catalysis system. Background technique [0002] Organic photochemistry refers to organic reactions under ultraviolet or visible light conditions. Compared with conventional synthesis methods, organic photochemical synthesis is environmentally friendly and sustainable, so it has broad development prospects. The most promising and most challenging topic in today's scientific development is how to use sunlight energy more effectively. It has been known that ultraviolet light has short wavelength and high energy. Most organic molecules can absorb ultraviolet light, but there is very little ultraviolet light that can be used in organic photochemistry in sunlight, and the high investment required for ultraviolet light reactors further limits its application in industrial production and experiments,...
