Abstract

The efficient assembly of an 18-membered macrocyclic peptide core was realized by a straightforward and convergent approach utilizing ring-closing metathesis of the corresponding linear tetrapeptides as the key transformation. This approach allowed for the facile preparation of a focused library of novel macrocycles that culminated in the discovery of a cyclophilin A inhibitor with a Kd=5.4μM.
