โœฆ Synopsis


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