The properties of β-cyanoenamines as analogs of amides are studied with derivatives of a rigid amino acid equivalent—Mcc = 1,2-diamino-3-cyanocyclopentene, prepared in two steps from methyl 2-(N-Boc-amino)-5-cyanopentanoate. Racemation of Mcc and incorporation into a cyclic pentapeptide are described.
