The isopropyl (2R,3R)- and (2S,3S)-cis-2,3-epoxybutanoates were prepared in three steps from l- and d-threonine, respectively. The racemic isopropyl trans-2,3-epoxybutanoate was obtained in two steps from trans-crotonic acid. The previous esters (four stereoisomers) could be easily differentiated by gas chromatography on a CP-Chirasil-Dex-CB capillary column.
