Abstract

Abstract Myers's methodology for enantioselective amino acid synthesis was employed to prepare the N-Boc didehydroleucine amide derivative 15 and to effect its conversion into the acylfuran intermediate 17. Coupling of 19 (R= H) with N-(isooctanoyl) serine provided the furan-based analogue 4 of eponemycin (de= 96%), a peptide epoxide with potent cytotoxic and anti-angiogenesis properties. In an identical fashion the corresponding unsaturated ...
