(R)-(-)-alpha-Methoxyphenylacetic acid Chemical Properties,Usage,Production
Chemical Properties
white fine crystalline powder or needles
Uses
(R)-(-)-α-Methoxyphenylacetic Acid is a useful synthetic intermediate. It is used as a reactant in the synthesis of dopamine receptor agonists. It can also be used to prepare hydroxytriamides as potent γ-secretase inhibitors.
General Description
(R)-(?)-α-Methoxyphenylacetic acid is a chiral derivatizating agent, which is employed for derivatizing enantiomers into diastereoisomers.
Purification Methods
Purify the acids by recrystallising from *C6H6/pet ether (b 80-100o). [Neilson & Peters J Chem Soc 1519 1962, Weizmann et al. J Am Chem Soc 70 1153 1948, Pirie & Smith J Chem Soc 338 1932, NMR: Dale & Mosher J Am Chem Soc 9 5 512 1973, for resolution: Roy & Deslongchamps Can J Chem 63 651 1985, Trost et al. J Am Chem Soc 1 0 8 4974 1986.] The racemic mixture has m 72o, b 121-122o/0.4mm, 165o/18mm (from pet ether) [Braun et al. Chem Ber 6 3 2847 1930]. [Beilstein 10 IV 566.]
