Merging Photoredox with Nickel Catalysis for Decarboxylative Arylation of Indole‐3‐Acetic Acids with Aryl Halides

Abstract

AbstractLate‐stage functionalization of indoles can be a valuable strategy for modifying different existing indolyl‐drugs and natural products to get their new analogues. In this study, we report the photoredox‐metal catalyzed decarboxylative arylation strategy of indole‐3‐acetic acids with aryl halides. Here, photoredox‐catalysis was synergistically merged with nickel‐catalysis for the synthesis of biologically important 3‐benzyl indoles with good functional group tolerance. The merit of this methodology is demonstrated by the synthesis of amino acid derived substrates 3 p, 3 v and 3 x.
