反応手順

Depending on the reaction conditions, hydrolysis of an ester, ortho ester or amide formed may be effected concomitantly or sequentially by standard methods. For example, when the protic solvent medium comprises acetic acid and sodium acetate and the ester substrate comprises 1,1-dimethoxy-1-(6-methoxy-2-naphthyl)prop-2-yl methanesulfonate, there is afforded the compound, methyl 2-(6-methoxy-2-naphthyl)propionate. The methyl ester is then hydrolyzed to the corresponding acid by contact with base. Alternatively, the α-arylalkanoic acid can be obtained by concomitant hydrolysis by maintaining the ester substrate in contact with a methanol-water solution containing sodium bicarbonate. Typically, 1,1-dimethoxy-1-(6-methoxy-2-naphthyl)prop-2-yl methanesulfonate is maintained in contact with a methanol-water solution containing sodium bicarbonate to afford 2-(6-methoxy-2-naphthyl)propionic acid.
