Abstract

(2R)-and (2S)-[1-13C]-2-amino-2-methylmalonate, probes for the stereochemical course of the serine hydroxymethyltransferase reaction, have been synthesised from bis-lactim ethers derived from valine and alanine. Direct acylation of the anion with diethyl carbonate gave the N-ethoxycarbonyl derivative rather than the required ethyl ester. The 13C-labelled carboxyl group was therefore Introduced via treatment of the anion with [1-13C]-acetyl ...
