A process for the preparation of optically active cyclohexylglycolate esters is described. The process utilizes carboxylic acid activation to couple (R)- or (S)-cyclohexylphenylglycolic acid (CHPGA) with 4-N,N-diethylamino butynol or other propargyl alcohol derivatives. The preparation of the hydrochloride salt is also described.
本发明描述了一种制备光学活性环己基乙醇酸酯的工艺。该工艺利用羧酸活化作用将(R)-或(S)-环己基苯基乙醇酸(CHPGA)与 4-N,N-二乙氨基丁炔醇或其他丙炔醇衍生物偶联。此外,还介绍了盐酸盐的制备方法。
