Abstract
Khayanolides A and B, two new rearranged phragmalin limonoids, were isolated as insect antifeedants together with two known rings B,D-seco compounds, methyl angolensate and its 6-hydroxy derivative from the ether extract of the stem bark of Khaya senegalensis. The structure of the new compounds was elucidated by spectroscopic means and the absolute structure of khayanolide A was established by X-ray analysis and CD study. The antifeedant activity is also reported.
