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

Oxidant-dependent Cu-catalyzed alkynylation and aminomethylation reactions have been achieved under facile and mild conditions. TMEDA coupled with various terminal alkynes via C-H bond cleavage in good yields using atmospheric oxygen as an oxidant. Switching from air to TBHP afforded aminomethylation products of terminal alkynes through C-C bond cleavage of TMEDA. The protocol provided a novel strategy to prepare bi/tridentate N-ligand.
