The present invention relates to a novel enantioselective method of preparing (S)- and (R)-enantiomers of N-3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]-6-5 methoxyphenyl}-1-[2,3-dihydroxy-propyl]cyclopropanesulfonamide, to novel intermediate compounds, and to the use of said novel intermediate compounds for the preparation of said (S)- and (R)-enantiomers of N-3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]-6-methoxyphenyl}-1-[2,3-dihydroxy-propyl]cyclopropanesulfonamide.
本发明涉及一种新的对称选择性方法,用于制备N-3,4-二氟-2-[(2-氟-4-碘苯基)氨基]-6-5-甲氧基苯基}-1-[2,3-二羟基-丙基]环丙磺酰胺的(S)-和(R)-对映体,以及新的中间体化合物,以及使用所述新的中间体化合物制备所述N-3,4-二氟-2-[(2-氟-4-碘苯基)氨基]-6-甲氧基苯基}-1-[2,3-二羟基-丙基]环丙磺酰胺的(S)-和(R)-对映体。
