from the highly efficient aza-Michael addition of different amines to α-trifluoromethyl acrylamide acceptors. Subsequent deprotection of the amino group furnishes the key common intermediate for the synthesis of other families of peptidomimetics: dipeptides, tripeptides, peptidomimetics containing a urea moiety, and structures containing two units of α-trifluoromethyl-β2-alanine. Finally, a conformational
