10 ml of a tetrahydrofuran solution containing 6.00 g was added, and then the temperature was gradually raised to -30°C. After the resulting dark yellow solution was cooled again to −78° C., a 15% hexane solution of triethylaluminum was added until the yellow color of the solution disappeared. The temperature of the reaction solution is -78℃
While keeping the temperature at 0°C, continue blowing in dry carbon dioxide and slowly raise the temperature to 0°C. The reaction solution is then poured into ice-saturated ammonium chloride solution. A 5% hydrochloric acid solution was added until the white solid was completely dissolved to make the solution acidic, and then extracted with ether. The ether layers were combined, washed with a saturated aqueous ammonium chloride solution, dried over anhydrous sodium sulfate, and then the solvent was removed under reduced pressure. Analysis of the residue by lH-NMR revealed that 2-triphenylsilyl-3-butenoic acid,
