A rapid on-bead convergent method for preparing branched peptides was reported. Linear peptides were prepared on Dbz resin and ligated various branched cores, including lysine dendrons and other dendritic compounds. Alongside microwave irradiation, <1.5 equiv of peptides is sufficient to afford 50-65% yields of pure branched peptides without chromatographic purification. Remarkably, the desired compounds were prepared within hours.
