(R)-(+)-Methyl p-tolyl sulfoxide Chemical Properties,Uses,Production
Uses
Used in asymmetric synthesis; adds diastereoselectively to carbony compounds, esters, imines, nitrones, and nitrile oxides.
General Description
(R)-(+)-Methyl p-tolyl sulfoxide may be used to prepare (R)-(+)-methyl 3,5-dimethoxy-6-[8-oxo-9-(p-tolylsulfinyl) nonyl] benzoate, an intermediate for (R)-lasiodiplodin synthesis. Its anions undergo addition reaction with nitrones to form optically active a-substituted N-hydroxylamines. (R)-(+)-Methyl p-tolyl sulfoxide also reacts with O-mesitylsulfonylhydroxylamine (MSH) to form (-)-(R)-S-methyl-S-p-tolylsulfoximine.
Synthesis
(R)-(+)-Methyl p-tolyl sulfoxide is prepared by the nucleophilic displacement of (-)- (1R,2S,5R)-Menthyl (S)-p-Toluenesulfinate with methyl Grignard with complete inversion of configuration at sulfur (eq 1).
Synthesis
Highly sensitive to air and moisture. Its generation and handling must be carried out under an inert atmosphere of nitrogen or argon. Normally, preparation is carried out immediately prior to use.
