Copper-Catalyzed Sequential Azomethine Imine-Alkyne Cycloaddition and Umpolung Thiolation Reactions

Copper-catalyzed sequential 1,3-dipolar cycloadditions of azomethine imines and alkynes and electrophilic thiolations are described. The C?S, C?N, and C?C bonds were simultaneously formed in one pot, leading to N,N-bicyclic pyrazolidinones in good to exce

Visible-Light Driven Selective C-N Bond Scission in anti-Bimane-Like Derivatives

In the present study, we report the photochemical transformation of pyrazolo[1,2-a]pyrazolone substrates that reach an excited state upon irradiation with visible light to initiate the homolytic C-N bond cleavage process that yields the corresponding N1-s

Copper(II)-catalyzed exo and enantioselective cycloadditions of azomethine imines

(Chemical Equation Presented) A strategy for exo and enantioselective 1,3-dipolar cycloaddition of azomethine imines to 2-acryloyl-3-pyrazolidinone is described. The corresponding cycloadducts are isolated with high diastereoselectivities (up to > 96:4 ex
