Bifunctional Imine Reductase Cascades for the Synthesis of Saturated <i>N</i>-Heterocycles.

ABSTRACT: Saturated N-heterocycles constitute a vital scaffold for pharmaceutical chemistry but are challenging to access synthetically, particularly asymmetrically. Here, we demonstrate how imine reductases can achieve annulation through tandem inter- and intramolecular reductive amination processes. Imine reductases were used in combination with further enzymes to access unsubstituted, α-substituted, and α,α'-disubstituted N-heterocycles from simple starting materials in one pot and under benign conditions. This work shows the remarkable flexibility of these enzymes to have broad activity against numerous substrates derived from singlular starting materials.
