Imine-Enamine Tautomerism -Nucleophilic Reactions of Imines [PDF]

Zeitschrift für Naturforschung B, 1982
Abstract A reinvestigation of the reactivity of N-isopropylidene cyclohexylamine to methyl acrylate by GC-MS analysis has shown that the major product is the β-aminoester (9) formed by the N-alkylation of cyclohexylamine which may be generated by a dimerisation-elimination sequence.

Imine reductases (IREDs)

Current Opinion in Chemical Biology, 2017
Imine reductases (IREDs) have emerged as a valuable new set of biocatalysts for the asymmetric synthesis of optically active amines. The development of bioinformatics tools and searchable databases has led to the identification of a diverse range of new IRED biocatalysts that have been characterised and employed in different synthetic processes.
