Abstract

A nine-step synthesis of 9-amino-4-methoxypyrido [3′, 2′: 4, 5] pyrrolo [1, 2-c] pyrimidine, a tricyclic ring system present in the marine alkaloids variolins is described. The natural marine products meridianins C–E have been synthetized for the first time starting from N- protected 3-acylindoles.
