A series of asymmetric reactions mediated by acyclic amino acid-based(thio)urea-tertiary amines,including amino acid-derived thiourea-tertiary amines,1 amino acid-derived urea-tertiary amines2 and dipeptide-derived(thio)urea-amide-tertiary amines,3 have been developed,thus providing diverse biologically valuable chiral molecules with satisfactory results.
