Kinetic resolutions of azomethine imines via copper-catalyzed [3 + 2] cycloadditions

An effective method has been developed for the kinetic resolution of racemic azomethine imines via [3 + 2] cycloadditions with alkynes catalyzed by a chiral copper complex. Efficient kinetic resolution is observed for a variety of N1 and C5 substituents o

Carbamoylation of Azomethine Imines via Visible-Light Photoredox Catalysis

A versatile and robust photocatalytic methodology to install the amide functional group into azomethine imine ions is described. This protocol is distinguished by its broad scope and mild reaction conditions, which are well suited for the preparation of s

Photocatalytic reductive radical-radical coupling of: N, N ′-cyclicazomethine imines with difluorobromo derivatives

A visible-light-induced difluoroalkylation of N,N′-cyclicazomethine imine was successfully realized through a novel photoredox radical-radical cross-coupling reaction. This developed protocol exhibits high functional group tolerance and affords a variety

[3 + 2]-Cycloadditions of Azomethine Imines and Ynolates

A novel [3 + 2]-cycloaddition between azomethine imines and lithium ynolates is described to synthesize bicyclic pyrazolidinones. These bicyclic pyrazolidinones are versatile intermediates to form β-amino acids and monocyclic pyrazolidinones. High diaster

Copper(I) acetate-catalyzed cycloaddition between azomethine imines and propiolates under additive-free conditions

Because propiolates easily undergo base-catalyzed self-Michael addition, most popular catalytic systems in CuAAC cannot be used in the cycloaddition between azomethine imines and propiolates, because such reactions usually require the use of tertiary amin

Highly regioselective [3 + 2] annulation of azomethine imines with 1-alkynyl fischer carbene complexes to functionalized N,N-bicyclic pyrazolidin-3-ones

The highly regioselective [3 + 2] cycloaddition of azomethine imines to 1-alkynyl Fischer carbene complexes has been successfully realized under mild conditions. Oxidative demetalation of the newly formed pyrazolo-pyrazolone carbene complexes with pyridin
