Enantioselective syntheses of (R)-3-phenyl GABA, (R)-baclofen and 4-arylpyrrolidin-2-ones

Langlois, Nicole,Dahuron, Nathalie,Wang, Hai-Shan

, p. 15117 - 15126 (2007/10/03)

Enantioselective synthesis of (R)-4-amino-3-phenylbutyric acid and (R)-baclofen has been achieved through a diastereoselective conjugate addition of cyanide to enantiomerically pure 2-(2-arylethenyl)oxazolines, followed by chemoselective reduction into cyclic amidines.
