Asymmetric synthesis and pharmacology of methylphenidate and its para- substituted derivatives

We report the first asymmetric synthesis of the individual enantiomers of methylphenidate (1). From d-pipecolic acid, the (2R,2'R) and (2S,2'R) enantiomers of 1 were obtained in >99% optical purity while the (2S,2'S) and (2R,2'S) enantiomers of 1 were der
