catalyst for C‐3 alkylation of 1H‐indoles with various aliphatic primary and secondary alcohols including cyclic alcohols as well as benzylic alcohols. The selective synthesis of bisindolylmethane derivatives is also achieved from the same set of indole and alcohol just by altering the reaction parameters. Furthermore, the sustainable synthesis of C‐3 alkylated indoles directly from 2‐(2‐nitrophenyl)ethan‐1‐ol
Lend me your hydrogen! The first transition‐metal‐catalyzed alkylations of indoles with aliphatic amines proceeding under transfer hydrogenation conditions are developed (see scheme). This reaction is based on the borrowing hydrogen methodology.
