Abstract

Ene-reductases (EREDs) catalyze the reduction of electron-deficient C═C bonds. Herein, we report the first example of ERED-catalyzed net reduction of C═C bonds of enimines (α,β-unsaturated imines). Preliminary studies suggest their hydrolyzed ring-open ω-amino enones are the likely substrates for this step. When combined with imine reductase (IRED)-mediated C═N reduction, the result is an efficient telescoped sequence for the preparation of diastereomerically enriched 2-substituted saturated amine heterocycles.
