Webb18 nov. 2024 · The cooperative catalysis using NHC and copper catalyst was investigated ( Figure 4) [ 29, 30 ]. The catalytic reaction using alkyne 21, tosyl azide 22, and isatin-derived imine 23 was investigated by using NHC precursor A6 and CuI [ 29 ]. The spiro-azetidine oxindole 24 was obtained in 83% yield with 85:15 er. Webb1 aug. 2024 · Recent advances in the Hauser annulation.
