Beschreibung

Anwendung

(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.
