[Uses]

(S)-(-)-Methyl p-tolyl sulfoxide can be used as a nucleophilic reagent to synthesize:
  • Optically active β-disulfoxides by reacting with arenesulfinic esters via formation of α-sulfinylcarbanion.
  • α-substituted N-hydroxylamines by treating with nitrones via preparation of (S)-(-)-methyl p-tolyl sulfoxide anion.
  • 2-O-benzyl-3,4-O-isopropylidene-L-erythrose by one-carbon homologation of 2,3-O-isopropylidene-L-glyceraldehyde.
