Abstract
A practical strategy has been developed for preparation of α-aryl ester derivatives by using a visible-light-induced Meerwein cascade reaction. This method uses molecular oxygen as an oxidant at room temperature without the need of hazardous reagents or harsh reaction conditions and provides a straightforward approach to pharmaceutically and synthetically useful α-aryl esters in moderate to good yields from simple and readily available starting materials. Oxindoles were also prepared by this protocol. A new strategy for the synthesis of α-aryl esters has been reported. This protocol utilizes acrylonitrile as a “bridge molecule” to combine a visible-light-induced Meerwein reaction and a hydrolysis reaction to generate α-aryl esters. This method was also employed for the preparation of oxindoles.
