Neue Tetranortriterpenoide aus Melia azedarach Linn. (Meliaceae)
Kraus, Wolfgang,Bokel, Michael
, p. 267 - 275 (2007/10/02)
Chromatography of the petroleum ether and ether extracts from the fruit of Melia azedarach Linn. afforded six new tetranortriterpenoids 1-6 the structures of which have been determined on the basis of NMR, IR, and MS data.Oxidation of lactol 5 gave lactone 2. 1 and 2 gave 3 and 4, resp., on methanolysis followed by acetylation.
