benzimidazole heterocycle. Finally, the resin-bound N′-hydroxybenzimidamide functionality was reduced to an amidine via 1 M SnCl2·2H2O in DMF prior to resin cleavage to release final product. This procedure permits the straightforward synthesis of aminoacids or peptides that are N-terminally capped by a phenylbenzimidazole-amidine ring system. Employing this protocol, a series of amino acid–phenylb
