Control of stereochemistry was achieved by a combination of Sharpless epoxidalion followed by catalytic hydrogenolysis of the introduced benzylic epoxide oxygen bond. Also, the coupling of organic compounds in the presence of palladium with enantiopure 2-(3-iodophenyl)propanoic and 2-(4-iodophenyl)propanoic acids, prepared by the methodology above, is a general method for the synthesis of optically active
(S)-2- [4'-(2″-甲基丙基)苯基丙酸(布洛芬)和(S)-2-(3'-苯甲酰基苯基)丙酸(酮洛芬)已经以高对映体过量的方式合成。立体化学的控制是通过Sharpless环氧化作用结合,然后对引入的苄基环氧化物氧键进行催化氢解来实现的。另外,通过以上方法制备的在钯存在下的有机化合物与对映纯的2-(3-碘苯基)丙酸和2-(4-碘苯基)丙酸的偶联是合成光学活性芳基丙酸的一般方法。酸。
