A visible-light-mediated, mild and one-pot three-component reaction in the presence of organophotoredox catalyst Eosin Y using EtOH:H2O as reaction medium for the synthesis of 3-functionalized indole derivatives was developed. Visible light used in the protocol is green, inexpensive, readily available energy source. The sustainable reagents make the protocol compatible with green chemistry demands.
