Research Progress in the Synthesis of Tetrahydroquinoline Derivatives from N,N-Dialkyl Aromatic Amines
Tetrahydroquinoline derivatives are an important class of nitrogen-containing heterocyclic compounds.The classic Povarov reaction in the synthesis of tetrahydroquinoline derivatives has the problem of limited substrate applicability.In recent years,research results on the synthesis of tetrahydroquinoline derivatives from N,N-dialkyl aromatic amines with olefins or maleimides have the characteristics of wide substrate applicability and strong atomic economy.
