of a ketene intermediate has led to an effective synthesis of samples of the amino acid proline which are stereospecifically labelled on the β-carbon. Since samples of stereospecifically labelled pyroglutamic acid derivatives are prepared in the route, other stereospecifically labelled, biologically important amino acids may be accessed by the synthesis.

were then converted into (2S,3S)-[3-(2)H1]- and (2S,3R)-[2,3-(2)H2]-proline, 1a and 1b respectively. The second synthesis provides (2S)-[3,3-(2)H2]-, (2S,3S)- and (2S,3R)-[3-(2)H1]-proline, 1d, 1a and 1c respectively, and has as its key step the highly stereoselective hydrolysis of the silylenol ethers 14 and 14a respectively in which deuteriation or protonation occurs from the re-face of the enol ether
