N2 - Following a preliminary comunication on Asteriscunolide A (the first reported natural humulanolide), three more configurationally and/or conformationally isomeric Asteriscunolides ( B, C and D ) from the same plant (Asteriscus aquaticus L.) are described. The absolute configurations and the stable conformations of all four Asteriscunolides are established by an array of spectroscopic methods (CD, 1H and 13C NMR) without resorting to X ray analysis. © 1984.
