Visible‐Light‐Mediated Cycloaddition of Azobenzenes and Nonstabilized Azomethine Ylides to Access 1,2,4‐Triazolidines

Advanced Synthesis & Catalysis, 2023
A visible‐light‐mediated cycloaddition of azobenzenes and nonstabilized azomethine ylides has been developed to access 1,2,4‐triazolidines. With readily available organic dye rose Bengal as a photocatalyst and alkyl tertiary amines as precursors for ...

β-Substituted Alkenyl Heteroarenes as Dipolarophiles in the Cu(I)-Catalyzed Asymmetric 1,3-Dipolar Cycloaddition of Azomethine Ylides Empowered by a Dual Activation Strategy: Stereoselectivity and Mechanistic Insight.

Journal of the American Chemical Society, 2021
The catalytic asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides with various electron-deficient alkenes provide the most straightforward protocol for the preparation of enantioenriched pyrrolidines in organic synthesis.
