Abstract
The title d-seco limonoid, named 1,3,7-trideacetyl-khivorin (systematic name: 14,15Β:21,23-diepoxy-1,3,7-trihydroxy-4,4,8-trimethyl-d-homo-24-nor- 17-oxochola-20,22-diene-16-one), C26H36O7, was isolated from the stem bark of African mahogany Khaya senegalensis (Meliaceae). The four fused six-membered rings adopt chair, chair, boat and half-chair conformations. The five-membered furan ring is disordered by a 180° rotation about the bond linking it to the pyran ring. The crystal structure is stabilized by strong classical O - H⋯O hydrogen-bond inter-actions to form a network.
