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
Visible-Light-Mediated α-Amino Alkylation of Azomethine Imines: An Approach to N-(β-Aminoalkyl)pyrazolidinones
Matsuo, Bianca T.,Correia, José Tiago M.,Paix?o, Márcio W.

Herein, a mild and robust photocatalytic protocol for the combination of amino and pyrazolidinone functionalities through a radical α-amino alkylation of azomethine iminium ions is demonstrated. This method presents a high functional group tolerance provi
Asymmetric [3 + 2] Cycloaddition of Methyleneindolinones with N,N′-Cyclic Azomethine Imines Catalyzed by a N,N′-Dioxide-Mg(OTf)2 Complex
Yin, Chengkai,Lin, Lili,Zhang, Dong,Feng, Juhua,Liu, Xiaohua,Feng, Xiaoming
, p. 9691 - 9699 (2015/10/12)
A highly efficient chiral N,N′-dioxide-Mg(OTf)2 catalyst system has been developed for the asymmetric 1,3-dipolar cycloaddition between methyleneindolinones and N,N′-cyclic azomethine imines. The desired pyrazolidine products with contiguous qu
Phosphine-catalyzed [3+2] cycloaddition reactions of azomethine imines with electron-deficient alkenes: A facile access to dinitrogen-fused heterocycles
Li, Zhen,Yu, Hao,Liu, Honglei,Zhang, Lei,Jiang, Hui,Wang, Bo,Guo, Hongchao

An efficient method for the phosphine-catalyzed [3+2] cycloaddition reaction of azomethine imines with diphenylsulfonyl alkenes to give dinitrogen-fused bi- or tricyclic heterocyclic compounds in high yields has been described. Moreover, two phenylsulfony
Enantioselective copper-catalyzed [3+3] cycloaddition of azomethine ylides with azomethine imines
Guo, Hongchao,Liu, Honglei,Zhu, Fu-Lin,Na, Risong,Jiang, Hui,Wu, Yang,Zhang, Lei,Li, Zhen,Yu, Hao,Wang, Bo,Xiao, Yumei,Hu, Xiang-Ping,Wang, Min

The more dipoles, the merrier: An asymmetric [3+3] cycloaddition of azomethine ylides derived from imines 1 with azomethine imines 2 in the presence of a chiral ferrocenylphosphine-copper catalyst afforded highly functionalized heterocyclic products 3 in high yield with excellent enantio- and diastereoselectivity (see scheme; DBU=1,8-diazabicyclo[5.4.0]undec-7-ene). The 1,3-dipolar reaction partners can be readily prepared from aldehydes. Copyright
Copper(I) acetate-catalyzed cycloaddition between azomethine imines and propiolates under additive-free conditions
Shao, Changwei,Zhang, Qun,Cheng, Guolin,Cheng, Chuanjie,Wang, Xinyan,Hu, Yuefei
, p. 6443 - 6448 (2013/10/21)
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
A new copper-catalyzed [3 + 2] cycloaddition: Enantioselective coupling of terminal alkynes with azomethine imines to generate five-membered nitrogen heterocycles
Shintani, Ryo,Fu, Gregory C.
, p. 10778 - 10779 (2007/10/03)
A copper-catalyzed method for the regioselective 1,3-dipolar cycloaddition of azomethine imines to terminal alkynes has been developed. Through the use of a chiral phosphaferrocene-oxazoline ligand, a wide range of substrates can be coupled to generate us
