Synthesis and reactions of new 2-substituted 5-phenyl-6-oxa-4-azaspiro[2,4]-hepten-7-one derivatives

Synthesis, reactions and relative configurations of new 2-halogen-, 2-acetyl- and 2-pivaloyl-substituted 5-phenyl-6-oxa-4-azaspiro[2,4]hepten-7-one derivatives 1a-h as potential precursors of 1-aminocyclopropanecarboxylic acids are described.

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.
