Decatungstate‐Photocatalyzed Diastereoselective Dearomative Hydroalkylation of Indoles

Abstract

In this study, we present an efficient and straightforward dearomative hydroalkylation of indoles. By utilizing alkanes or ethers as alkyl radical sources and employing TBADT as a cost‐effective photocatalyst for direct hydrogen atom transfer (HAT), we achieved successful conversion of these heterocyclic derivatives into 2‐alkylindolines with good to excellent yields and high diastereoselectivity under mild reaction conditions.
