外文摘要：Herein,we report the first visible-light photoredox-catalyzed carboxylation of aryl epoxides with CO2 to synthesize hydroxy acid derivatives.A variety of valuable β-,γ-,δ-,ε-hydroxy acid derivatives are obtained in moderate to high yields under mild conditions.This protocol shows noteworthy functional-group compatibility,high chemo-and regioselectivities under transition-metal-free conditions with an inexpensive organo-dye as photosensitizer.Mechanistic studies indicate that the benzylic carbanion is generated as an intermediate via the sequential single electron transfer(SSET)process.
