multicomponent reaction that generates functionalized 1,4-dicarbonyl motifs via formal hydrocarbonylation of activated alkynes with propargylamines and water under metal-free conditions. This novel synthesis method utilizes propargylamines and water as carbonyl and proton precursors in which propargylamines are activated in situ by alkynes for α-C(sp3)–H activation and C–N bond cleavage. This method
