A highly efficient and enantio selective synthesis of (S)-3-amino-5-methylhexanoic acid 1 (Pregabalin) is reported. Evans enolate based asymmetric alkylation reaction was used as the key step to set up the required chirality. This procedure allows the rapid process to provide the (S)-(+)-Pregabalin 1 in excellent overall yields and purity.
