Abstract

Application of the Miyaura–Hayashi rhodium-catalysed addition of aryl boronic acids to acyclic unsaturated esters featuring basic centres to yield γ-amino butyric acids incorporating a substituted β-phenyl group is described. Unoptimised isolated yields and enantiomeric excesses vary from moderate to excellent, and the method tolerates a variety of substitution patterns and a range of functionality.

Key words

rhodium - asymmetric 1,4-addition - drugs - γ-aminobutyric acid - synthesis
