title: A new xenicane norditerpene from the Indian marine gorgonian Acanthogorgia turgida.
abstract: Chemical investigation of the liposoluble extract of the gorgonian Acanthogorgia turgida, from Indian coasts, led us to isolate a new xenicane-based norditerpene, isoacalycixeniolide-A (1), along with the known structurally related compounds 2-6. The structure of the norditerpene (1) was elucidated by spectral methods (mainly by NMR techniques), whereas the absolute stereochemistry was suggested by the application of circular dicroism methodology.
