Abstract

The synthesis of both the (E)-and (2)-isomers of the unnatural amino acid, 2-phenyl-l- aminocyclopropane-l-carboxylic acid (cyclopropylPhe, Figure 11, has been accomplished in racemic fashion.'To date, only (2)-cyclopropylPhe has been synthesized in diastereoenriched form; 2 (E)-and (2)-cyclopropylPhe have been resolved via the agency of (-)-brucine: and (-)-0, O-dibenzoyltartaric acid,'respectively. In recent years there has been ...
