Abstract:
The combined hexane-CH(2)Cl(2) extract of the stembark of the Madagascan Meliaceae Neobeguea leandreana yielded three novel phragmalin limonoids, leandreanins A (1), B (2), and C (3). Leandreanins A (1) and B (2) are rare seco-ring D 17-keto compounds related to pseudrelone B, while leandreanin C (3) has an unprecedented acetoxy functionality at C-19.
