Catalytic imine–imine cross-coupling reactions

Chem. Commun., 2014
We report here efficient catalytic imine-imine cross-coupling reactions based on an umpolung strategy; an imine bearing a 9-fluorenyl moiety on its nitrogen atom, which acted as a nucleophile, reacted with another imine to afford an imine-imine cross-coupling adduct in high yield.

Imines

2022
This chapter explores the synthesis of amines. It explains how amines are accessible from three main sources: basic amine building blocks, synthetizsation of the amino group to a suitable precursor, and yielding more complex amines after being alkylated.

Isomerization of imines in platinum-imine complexes

Inorganica Chimica Acta, 1986
Abstract Multinuclear 1H, 13C and 195Pt spectroscopy provides strong evidence for E-Z isomerization of imine ligands coordinated to platinum(II) of the type trans [PtCl2(η2-C2H4)(imine)].

Dynamic imine chemistry

Chemical Society Reviews, 2012
Formation of an imine--from an amine and an aldehyde--is a reversible reaction which operates under thermodynamic control such that the formation of kinetically competitive intermediates are, in the fullness of time, replaced by the thermodynamically most stable product(s).

The Catalytic Acylcyanation of Imines

Chemistry – An Asian Journal, 2008
AbstractThe catalytic acylcyanation of aldimines with acylcyanides and a direct three‐component variant involving the generation of an imine in situ have been developed. Furthermore, a highly enantioselective version has been established, culminating in the first organocatalytic asymmetric three‐component Strecker reaction.

Radical Aminomethylation of Imines

The Journal of Organic Chemistry, 2014
Taking advantage of the high level of performance of N-alkoxycarbonyl-imines, we achieved the first example of addition of the aminomethyl radical to imine. The reaction efficiency depended on the structure of the radical precursor, whether it is an iodide or a xanthate, and an electron-withdrawing group on the nitrogen atom of the radical.

Enantioselective imine reduction catalyzed by imine reductases and artificial metalloenzymes

Org. Biomol. Chem., 2014
Adding value to organic synthesis. Novel imine reductases enable the enantioselective reduction of imines to afford chiral amines. Likewise, novel bioinspired artificial metalloenzymes can perform the same reaction as well. Remarkable recent examples are herein discussed.

Asymmetric Hydrogenation of Imines

2013
Homogeneous catalytic asymmetric hydrogenation has evolved into a significantly useful methodology for the preparation of enantiopure compounds. Significant advances in asymmetric hydrogenation of imines have enabled a straightforward and powerful approach to various chiral amines.
