investigation of a Fijian ascidian, Polyandrocarpa sp., has resulted in the isolation of two new 2-aminoimidazolone-derived compounds, polyandrocarpamines A (1) and B (2). The structures of these unique metabolites were determined by the interpretation of spectroscopic data and confirmed by total synthesis. The stereospecific synthesis of 1 was accomplished using aldol condensation chemistry to generate an
