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
