A new visible light photocatalytic multicomponent reaction (MCR) involving N-alkyl-N-methylanilines, N-isocyanoiminotriphenyl phosphorane, and carboxylic acids leading to 1,3,4-oxadiazole derivatives is herein reported. The developed mild reaction conditions enable a broad substrate scope and a good functional group tolerance, as further highlighted in the late stage functionalization of amino acids and drugs. Additionally, a 2-step one-pot protocol for the obtention of non-symmetrical diacylhydrazines is also reported as an expeditious and green synthetic approach to such valuable scaffolds.
