A visible/solar-light-induced electron-donor-acceptor (EDA)-aggregated/mediated radical cyclization between (E)-2-(1,3-diarylallylidene)malononitriles and thiophenols leads to poly-functionalized pyridines. The two reacting partners form an EDA complex that absorbs light triggers the single-electron transfer (SET) generate a thiol radical, which undergoes addition/cyclization with dicyanodiene through formation of C-S C-N bonds.

Cu(OTf)₂-catalyzed multicomponent reactions

Beilstein Journal of Organic Chemistry, Год журнала: 2025, Номер 21, С. 122 - 145

Опубликована: Янв. 14, 2025

This review reports the achievements in copper(II) triflate-catalyzed processes concerning multicomponent reactions, applied to synthesis of acyclic and cyclic compounds. In particular, for heteropolycyclic systems mechanistic insights were outlined as well cycloaddition aza-Diels–Alder reactions included. These strategies have gained attention due their highly atom- step-economy, one-step multi-bond forming, mild reaction conditions, low cost easy handling.
