Recombinant 4-hydroxyacetophenone monooxygenase (HAPMO) from Pseudomonas fluorescens ACB has been tested as a catalyst in sulfoxidation reactions on a set of aromatic sulfides. With a few exceptions, excellent enantioselectivities in the synthesis of chiral phenyl and benzyl sulfoxides were achieved. The bacterial Baeyer-Villiger monooxygenase was also shown to accept racemic sulfoxides, a prochiral diketone and an organoboron compound as substrates. This study demonstrates the great biocatalytic potential of this novel oxidative enzyme. (c) 2005 Elsevier Ltd. All rights reserved.

Abstract
Recombinant 4-hydroxyacetophenone monooxygenase (HAPMO) from Pseudomonas fluorescens ACB has been tested as a catalyst in sulfoxidation reactions on a set of aromatic sulfides. With a few exceptions, excellent enantioselectivities in the synthesis of chiral phenyl and benzyl sulfoxides were achieved. The bacterial Baeyer-Villiger monooxygenase was also shown to accept racemic sulfoxides, a prochiral diketone and an organoboron compound as substrates. This study demonstrates the great biocatalytic potential of this novel oxidative enzyme. (c) 2005 Elsevier Ltd. All rights reserved.File in questo prodotto:
