Total synthesis of cytotoxic marine alkaloids, lamellarins D, L, and N, has been achieved by using Hinsberg-type pyrrole synthesis and palladium-catalyzed Suzuki–Miyaura coupling of the 3, 4-dihydroxypyrrole bistriflate as the key reactions. The total yields of lamellarins D, L, and N from the common intermediate are 54, 58, and 50%, respectively.
