(3aS,4S,5S,6E,11S,11aS)-5-(Acetyloxy)-2,3,3a,4,5,8,9,10,11,11a-decahydro-11-hydroxy-3,10-bis(methylene)-4-[[(Z)-2-methyl-1-oxo-2-butenyl]oxy]-2-oxocyclodeca[b]furan-6-carboxylic acid methyl ester

A Daphnandra alkaloid, this base is found in D. repandula. It gives a crop of colourless crystals from MeOH and has [α]²⁰_D - 74.6° (CHCI3) or - 78.4° (C6H6). The hydrochloride is laevorotatory with [α]²⁰_D - 141° and the hydrobromide and sulphate are both crystalline and both decompose above 200°C. The alkaloid behaves as a diacidic base, contains three methoxyl groups and two methylimino groups, but no methylenedioxy groups.
