AbstractTitle compound 1b (purity > 99%, 99.6%ee) is synthesized (100g scale) from commercial 3-bromo-pyruvic acid in six steps with an overall yield of 16%. The sequence is operationally simple and devoid of chromatographic purifications. Key step is the asymmetric hydrogenation of a substrate with substrate with functionality.
