N-Fmoc-protected(α-aminoacyl)benzotriazoles 1a-d readily afford chiral N-Fmoc-protected-α-dipeptides 2a-f (77-89%). Compounds 2a-f are further converted into N-Fmoc-protected(α-dipeptidoyl)benzotriazoles 3a-f (71% average yield). Under mild microwave irradiation, 3a-f are used in solid-phase peptide segment condensation syntheses to give tri-, tetra-, penta-, hexa-, and heptapeptides (20-68%).
