- Facile Synthesis of β-Keto Sulfones Employing Fenton's Reagent in DMSO
-
A new facile method for the synthesis of β-keto sulfones employing xanthates, DMSO, and Fenton's reagent is described. The reaction proceeds under very mild conditions providing a cost-effective straightforward approach to various β-keto sulfones in high yields.

Compound formula I: wherein: X1 and X2 may be either (a) C and O, (b) N and N, or (c) C and NH, where the dotted bonds represents a double bond in the appropriate location; R1 and R2 are independently selected from hydrogen, an optionally substituted C1-7 alkyl group, an optionally substituted C3-20 heterocyclyl group, or an optionally substituted C5-20 aryl group, or may together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; RN1 is selected from hydrogen and an optionally substituted C1-4 alkyl group; RC1 is selected from an optionally substituted C1-7 alkyl group, an optionally substituted C3-20 heterocyclyl group, or an optionally substituted C5-20 aryl group; or RN1 and RC1 may together form an optionally substituted C2-4 alkylene group.

- Alternative approach to the synthesis of optically active β-keto sulfoxides by furylhydroperoxides enantioselective oxidations
-
Enantiomerically enriched β-keto sulfoxides are obtainable by an alternative method to the classical reaction of the enantiomerically pure α- sulfinyl anion with esters or by Anderson's synthesis, through Sharpless modified kinetic resolution of racemic β-keto sulfoxides. High e.e.s are achieved by combining asymmetric oxidation and kinetic resolution using furylhydroperoxides as oxidants.
