Caribenols A and B, sea whip derived norditerpenes with novel tricarbocyclic skeletons.
The extraction of two specimens of Pseudopterogorgia elisabethae, each collected from a different location at the San Andrés Archipelago, afforded two new norditerpenes, caribenols A (1) and B (2). Metabolites 1 and 2 contain unusual carbon skeletons that are previously undescribed and therefore constitute new classes of C19 rearranged terpenes. Their molecular structures were established by a combination of single-crystal X-ray analysis and comprehensive 2D NMR measurements.
