摘要

Photolysis at 254 nm of neat (no solvent) unsymmetrical diacyl peroxides derived from cyclopropane carboxylic acids and l-aspartic acid generates protected β- cyclopropylalanines in reasonable yields. Orthogonally protected 3-(trans-2- aminocyclopropyl) alanine (21), a key constituent of the antitumor agent belactosin A, as well as protected hypoglycin A (26), a causative agent of Jamaican vomiting sickness, is ...
