Synthesis of (E)- and (Z)-Cyclopropyl-3-chloroalanine

Both stereoisomers of cyclopropyl-3-chloroalanine (1) were synthesized by diazomethane cyclopropanation of the appropiate oxazolones (2).X-ray crystallographic analysis elucidated the configurations of 1 and gave some insight into its possible conformational preferences.
