Biocatalytic Michael‐Type Additions of Acetaldehyde to Nitroolefins with the Proline‐Based Enzyme 4‐Oxalocrotonate Tautomerase Yielding Enantioenriched γ‐Nitroaldehydes

Abstract

Call me Michaelase: The enzyme 4-oxalocrotonate tautomerase (4-OT) promiscuously catalyzes the Michael-type addition of acetaldehyde to a collection of aromatic and aliphatic nitroolefins with high stereoselectivity producing precursors of γ-aminobutyric acid (GABA) analogues (see scheme).
