Abstract

An efficient method was developed for the construction of N-short-chain ether-attached carbonyl group-substituted indazoles. The visible-light-induced three-component reactions of α-diazoesters, indazoles, and cyclic ethers, under extremely mild conditions, led to the corresponding mixture of N 1 and N 2 short-chain ether-substituted indazoles in good to excellent yields.
