Abstract

2-Deutero-3-fluoro-L-alanine is converted into its D-isomer in an asymmetrical manner. In this process, the L-isomer is reacted with sodium nitrite to give the corresponding L-2-deutero-2-halo-3-fluoro-propionic acid in solution in an aqueous hydrohalic acid. This L-2-deutero-2-halo-3-fluoropropionic acid is then reacted either with ammonia or with sodium azide with replacement of the 2-halogen substituent by a 2-azido group and subsequent catalytic hydrogenation to give 2-deutero-3-fluoro-D-alanine. 2-Deutero-3-fluoro-L-alanine can be converted into pharmaceutically acceptable salts. The resulting compound can be used for inhibition of the growth of Gram-positive and Gram-negative pathogenic bacteria. [GB1488332A]
