Enantioselective Synthesis of Dihydrofuranylglycine, Furanylglycine, Furanylalanine and homo-Furanylalanine Derivatives

Enantiomerically pure nor-furanomycin, furanylglycine, furanylalanine and homo-furanylalanine derivatives were prepared from appropriate amino acid derived dienes using ring-closing ­metathesis as the key step.
