Chemoenzymatic cascades offer a simple and efficient way to rapidly build structural complexity. A three-step one-pot process is reported in which a Wittig reaction, chiral-thiourea-mediated asymmetric conjugate addition, and a bioreduction step were combined to access chiral nitro alcohols from commercially available benzaldehyde derivatives in good overall yields and excellent diastereomeric and enantiomeric ratios.
