Descrizione generale
3-Methyl-2-oxindole (MOI) is a 3-substituted-2-oxindole. It is reported to be formed during the oxidation of indole-3-acetic acid in the presence of FeII under aerobic conditions. MOI undergoes asymmetric anti-Mannich-type reaction with N-tosyl aryl aldimines in the presence of alkaloid cinchona derivatives to form anti-3,3-disubsituted 2-oxindole derivatives. It also undergoes asymmetric hydroxyamination with nitrosoarenes to form N-nitroso aldol products.
Applicazioni
3-Methyl-2-oxindole may be used in the preparation of 3-hydroxy-3-methyl-2-oxindole.
- Reactant for enantioselective α-amination reactions
- Reactant for aldol reaction with glyoxal derivatives
- Reactant for amine thiourea catalyzed conjugate addition to α,β-unsaturated aldehydes
- Reactant for O-acetylation reactions
- Reactant for preparation of a disubstituted oxoindole by using rhodium-catalyzed cyclopropanation/ring-opening reactions

A series of cinchona alkaloid derivatives were used to catalyze the asymmetric anti-Mannich-type reaction of 3-methyl-2-oxindole with N-tosyl aryl aldimines. The resulting anti-3,3-disubstituted 2-oxindole products were obtained in good yields (up to 92%) with high diastereo- and enantioselectivities (anti/syn up

The toxicity of 3-methylindole (3 MI), a selective pneumotoxin, is dependent upon cytochrome P450-mediated bioactivation 3. Using vaccinia-expressed P450 enzymes, the metabolites of radiolabeled 3 MI produced by 14 individual P450s were identified and quantified by high performance liquid chromatography.
