A practical and scalable synthesis of in vivo sphingosine-1-phosphate lyase inhibitor LX2931 (1) is described. The synthetic route features an improved Buchi cyclocondensation of 2-ethoxyacrylonitrile (3) with either 1-amino-1-deoxy-d-fructose acetat

[reaction: see text] A novel crystallization-induced chiral inversion of (S)-2-bromo-3-phenylpropanoic acid to its (R)-enantiomer with excellent enantiomeric excess (96-99%) is achieved. Optically pure (S)-2-acetylthio-3-phenylpropanoic acid can be p

The carboxylate anion has been used as a directing group to effect selective ortho-substituted derivatives 3 (>99:1 selectivity 50−80% yield). The solvent, base, and equivalents of base are the determining factors for the success of this reaction.
