Abstract

A small library of guanidino-lactams were synthesized in four steps and good overall yields by following the routes: preparation of guanylating agents, synthesis of protected guanidino-acids, cyclization to fully protected guanidino-lactams, and deprotection to the target compounds. The guanidino-lactams were assayed as antimicrobials on E. coli showing no significant antibiotic activity.
