respectively, and dimethyl (2S,3R)- and (2R,3R)-[2-2H1]-homocitric lactones, 11b and 11c respectively, have been synthesised from shikimic acid and [2-2H]-shikimic acid by a route which defines the stereochemistry of the two chiral centres in each compound. The NMR spectra of these products will enable the stereochemistry of the biological reaction catalysed by homocitrate synthase and by the protein from the
