Abstract

Copper(I)-catalyzed (4+3)-cycloaddition of 4-indolylcarbinols with aziridines has been accomplished to furnish azepinoindoles. The chirality transfer, substrate scope, functional group tolerance, natural product modification and tandem C–C/C–N bond formation are the important practical features. [ABSTRACT FROM AUTHOR]

Abstract

Directing group assisted C−H bond functionalization using transition‐metal‐catalysis has emerged as a reliable synthetic tool for the construction of regioselective carbon‐carbon/heteroatom bonds. Off late, "in/on water directed transition‐metal‐catalysis", though still underdeveloped, has appeared as one of the prominent themes in sustainable organic chemistry. This article covers the advancements, mechanistic insights and application of the sustainable directed C−H bond functionalization of (hetero)arenes in/on water in the presence of transition‐metal‐catalysis.
