Synthesis of cyclopropene α-amino acids via enantioselective desymmetrization

Zhang, Fan,Fox, Joseph M.

, p. 2965 - 2968 (2006)

The preparation of cyclopropene α-amino acids via the enantioselective desymmetrization of cyclopropene bis-carboxylic acid derivatives is described. The amino acids are stable to harsh reaction conditions, and a derivative has been incorporated into a tripeptide using conventional methods for peptide synthesis.
