Unprecedented Stylissazoles A–C from <i>Stylissa carteri</i>: Another Dimension for Marine Pyrrole‐2‐aminoimidazole Metabolite Diversity

Abstract

No cramping this “styl”: The three title compounds, dimeric pyrrole-2-aminoimidazole alkaloids, were isolated from the marine sponge Stylissa carteri collected in the Solomon Islands. The isolated compounds are exclusively NC-bonded “dimers”, which indicates a different mode of dimerization and adds another dimension to the molecular diversity of pyrrole-2-aminoimidazole alkaloids.
