Acyclic α-nitroketones are easily obtained in one pot, through a solvent-free procedure by nitroaldol (Henry) reaction on neutral alumina, then in situ oxidation of the nitroalkanol using wet alumina supported chromium(VI) oxide.

Peptide-based catalysts have been developed that promote the asymmetric Michael addition of nitroalkanes. The most effective peptides contain a beta-turn structural element as well as a basic histidine and an arylsulfonamide-protected arginine. Excellent yields with enantioselectivities of up to 74% ee have been observed. (c) 2007 Elsevier Ltd. All rights reserved.
