An efficient and convenient methodology for the synthesis of the 3-(trans-2-aminocyclopropyl) alanine and 3-(trans-2-nitrocyclopropyl) alanine moieties found in the core of belactosin A and hormaomycin, respectively, is reported. By using an enantioenriched substituted α-nitro diazoester in a diastereoselective intramolecular cyclopropanation reaction, the trans-nitrocyclopropyl alanine moiety can
