| 摘要 |
This invention relates to the preparation of (R)-(-)-3-(carbamoylmethyl)-5-methylhexanoic acid, in particular, the resolution of the acid racemate by means of salification with optically active amines and subsequent acidification to give the (R) enantiomer of the acid; this invention also concerns the salt intermediates formed with said amines and the conversion of said (R)-(-)-3-(carbamoylmethyl)-5-methylhexanoic acid into biologically active molecules such as pregabalin. |
