YieldReaction ConditionsOperation in experiment
With water; lithium hydroxide; In tetrahydrofuran; methanol; at 20℃; for 4h; General procedure: [0069] As shown in the following Table 5, by using 1 mmol of optically active carboxylic acid esters, each of whichproduced an optically active carboxylic acid, a hydrolysis reaction of a carboxylic acid ester was performed. That is, 1mmol of the carboxylic acid ester and 4 mL of water were added to the ammonium pyrosulfate catalyst (5 mol%) obtainedin Example 1(1), and the mixture was heated at 80C for 9 to 20 hours while stirring was performed. The reaction mixturethus obtained was diluted with water and was then extracted with ethyl acetate. After organic layers were collected anddried with sodium sulfate, a crude product obtained by condensation under reduced pressure was purified by a columnchromatography, so that an optically active carboxylic acid was obtained. In addition, the optical purity of the reactionproduct was measured by a chiral HPLC. Characteristic chemical shifts (ppm) by 1H NMR (CDCl3) and the analyticalconditions of the chiral HPLC are shown below. In addition, the results are shown in Table 5.
