An efficient and convergent route was developed for the synthesis of a novel class of urea-based macrocyclic kinase inhibitors. The synthesis is featured with an efficient urea formation by using a key carbamate intermediate and with a smooth ring-closure olefin metathesis. Furthermore, the hydrogenations of the resulting olefins were investigated in this complex macrocyclic ring system.
