METHYL 3-HYDROXY-2-NAPHTHOATE Chemical Properties,Usage,Production
General Description
Methyl 3-hydroxy-2-naphthoate undergoes asymmetric oxidative coupling using mono-N-alkylated octahydrobinaphthyl-2,2′-diamine chiral ligands.
Synthesis
Methyl 3-hydroxy-2-naphthoate is obtained by reacting 3-hydroxy-2-naphthoic acid with methanol in sulphuric acid.3-hydroxy-2-naphthoic acid (1.00 g, 5.31 mmol) was dissolved in methanol (20 ml) and concentrated sulphuric acid (1 ml) and left to reflux overnight with stirring. The reaction mixture was washed with brine (2×10 ml) and extracted with ethyl acetate (3 × 10 ml) upon cooling. The organic extracts were collected, dried with magnesium sulphate and concentrated in vacuo to give the title compound as a yellow powder (976 mg, 91%): mp: 81℃(Lit.: 75 – 76℃);
