Abstract

Four oxygenated amorphane derivatives [(-)-(1R,2S,6R,10S)- 2alpha-acetoxyamorpha-4,7(11)-dien-8-one, (-)-(1R,2S,6R,10S)- 2alpha-acetoxy-11-methoxyamorpha-4,7-diene, (-)- (1R,2R,3S,6R,10S)-2alpha,3alpha-diacetoxyamorpha-4,7(11)-dien- 8-one and (-)-(1R,2R,3R,6R,9S,10R)2alpha,3alpha-diacetoxy- 9alpha-hydroxyamorpha-4,7(11)-dien-8-one] have been isolated from the Scottish liverwort Marsupella emarginata var. aquatica. Their structures were determined following extensive (mainly 1D and 2D NMR) spectroscopic studies.
