Starting from 'chiral-pool' derived γ-amino-β-ketosulfones, a facile synthesis of enantiopure α-amino ketones has been developed via an α-alkylation-desulfonation sequence. Extension of this methodology to enantiopure α-acetoxy ketone synthesis, however, have met with limited success.DOI...
β -Ketosulfones are an important class of oxygen-containing extremely versatile compounds in organic chemistry. They attract the interest of chemists due to their interesting biological properties and synthetic applications on natural products and organic compounds. In this review we summarise the method...
The screening of 144 microbial strains yielded several suitable biocatalysts for the asymmetric bioreduction of an allylic ketosulfone to its corresponding (R)-alcohol. The production of the desired enantiomer with elevated optical purity (ee > 90%) was achieved by the yeast strain Candida magnoliae...
