With the assistance of phosphorus trichloride, L-Valine (L-Val) was assembled into homopeptides and homocyclopeptides which were analyzed by electrospray ionization mass spectrometry (ESI-MS). On quenching with water or various alcohols, the reaction mixtures yielded the corresponding peptides or peptide esters and cyclopeptides, respectively. The formation of the products was proved by multistage electrospray ionization mass spectrometry (ESI-MS/MS).
