Abstract

Calyxamines A (1) and B (2) are 2,2,4,6,6-pentasubstituted Piperidine Alkaloids possessing novel carbon skeletons isolated from the marine Sponge Calyx podatypa collected in Puerto Rico. Their structures, after derivatization with trifluoroacetic acid, have been determined by a combination of X-ray and spectroscopic methods. A plausible biogenetic pathway to the calyxamines is suggested.
