L- and D-Amino acids which are stereoselectivelylabelled solely either in the 3-pro-R or in the 3-pro-S-positions have been prepared by a relatively short chemicalsynthesis in ee of 81 to 86%. This involves Sharpless' aminohydroxylation and cyclisation with inversion of stereochemistry at C-2 to give the stereoselectivelylabelled D- and L-aziridines and 10a and 10b, and 8a and 8b. These have previously

Stereospecificaily deuteriated isoserines 4, formed from enzymically prepared 3-deuteriated malic acids 2(X = OH) by Curtius rearrangement, have been converted to the deuteriated aziridines 7 and 9 which, on ring-opening and deprotection, yielded samples of the amino acids D-serine and D-cystine and the enzyme inhibitor–substrates D-β-chloroalanine and D-serine O-sulphate which are labelled Stereospecificaily at C-3 with deuterium.
