2-Amino-2-methylmalonic acid and both of its [1-13C]-enantiomers were synthesised and were then used to probe the stereochemical course and mechanism of serine hydroxymethyltransferase catalysed reactions; the pro-R carboxy group of 2-amino-2-methylmalonic acid was decarboxylated and was replaced by a proton with retention of configuration at C-2 to give (2R)-alanine.
