  A Novel Intermolecular Synthesis of γ-Lactones via Visible-Light Photoredox Catalysis

  摘要：

  Direct gamma-lactone formation via visible-light photoredox catalysis has been achieved efficiently including hydroxylalkylation of aromatic alkenes and transesterification. The present photocatalytic protocol has good regioselectivity and substrate compatibility, affording a novel way to intermolecular gamma-lactone synthesis by the reaction of styrenes with alpha-bromo esters in the absence of any external oxidants.
