Abstract
Khayanolides A and B, two new rearranged phragmalin limonoids, were isolate
d as insect antifeedants together-with two known rings B,D-seco compounds,
methyl angolensate and its 6-hydroxy derivative from the ether extract of t
he 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. (C) 2000 Elsevier Science Ltd. All rights reserved.
