  The invention provides a new enantioselective process for the preparation of (S)-pregabalin, or a pharmaceutical acceptable addition acid salt comprising: acid hydrolysis of the dioxolan ring of a chiral compound of general formula (I) to obtain compound of general formula (II); oxidation of compound (II) to obtain a compound of general formula (III) and transforming compound (III) into compound of general formula (IV); subjecting compound (IV) to basic hydrolysis to obtain a compound of general formula (V) which is reduced to obtain enantiomerically pure S-pregabalin. The invention also provides new chiral intermediates involved in the process.

  Rhod to addition: An efficient asymmetric conjugate‐addition reaction of alkenyltrifluoroborates and α,β‐unsaturated carbonyl compounds, as catalyzed by a rhodium–diene complex, was developed. The products were obtained in high yield and high levels of enantioselectivity. The methodology was applied to a concise synthesis of (S)‐pregabalin and (−)‐α‐kainic acid (see scheme).
