ABSTRACT:
(S)-Pregabalin, which has the chemical name (S)-(+)-3-(aminomethyl)-5-methylhexanoic acid, is useful in anticonvulsant therapy, primarily due a mechanism that serves to promote the production of gamma-amino butyric acid, an inhibitory neurotransmitter. The invention encompasses new processes for synthesizing (S)-Pregabalin. The invention also comprises certain new compounds that are useful synthetic intermediates in the synthesis of (S)-Pregabalin.
