This article presents a one-pot synthesis of nitrocyclopropanes via Michael addition initiated ring closure sequence reactions of bromonitroalkane to alpha,beta-unsaturated enones. Moderate to favorable yields (55-93%) and certain enantioselectivities were obtained with alpha-amylase from hog pancreas as the catalyst. This strategy utilizes the unnatural ability of enzymes to provide a convenient and biocatalytic method for green organic synthesis. (C) 2016 Elsevier B.V. All rights reserved.
