Novel pyrroles from the Oregon red alga Gracilariopsis lemaneiformis.
Two new pyrrole natural products have been isolated from the temperate-water red alga, Gracilariopsis lemaneiformis, as diacetate derivatives. The structures of these C- and N-alkylated pyrroles were determined by spectroscopic methods (principally high field nmr and ms) to be N-(2-acetoxy)-propyl-2-(2-acetoxy)-acetopyrrole and N-(2-acetoxy)-ethyl-2-(2-acetoxy)-acetopyrrole.
