The invention relates to a leucine derivative, N-2[(S)-2-N-formylamino-4-methyl pentanoic acid (S)-1-[[3(S)-hydroxy-5-oxo-4-hexyl methyl]dodecyl ester] amino-4-methyl pentanoic acid (S)-1-[(2S, 3S)-3-hexyl-4-oxo-2-oxetanyl]methyl dodecyl ester of Formula (I), and process for isolating it. More particularly, it relates to the preparation of pure orlistat, which is (S)-2-Formylamino-4-methyl pentanoic acid (S)-1-[(2S, 3S)-3-hexyl-4-oxo-2-oxetanyl]methyl]dodecyl ester. The invention also relates to the use of the Compound of Formula (I) as reference standard or reference marker for checking the purity of orlistat.
该发明涉及一种亮氨酸衍生物,即N-2[(S)-2-N-甲酰氨基-4-甲基戊酸(S)-1-[[3(S)-羟基-5-羰基-4-己基甲基]十二烷酸酯]氨基-4-甲基戊酸(S)-1-[(2S, 3S)-3-己基-4-氧代-2-氧环戊基]甲基十二烷酸酯的化合物(I)及其分离方法。更具体地,涉及制备纯奥利斯塔特,即(S)-2-甲酰氨基-4-甲基戊酸(S)-1-[(2S, 3S)-3-己基-4-氧代-2-氧环戊基]甲基十二烷酸酯。该发明还涉及将化合物(I)作为奥利斯塔特纯度检测的参考标准或参考标记的用途。
