Cabraleahy­droxy­lactone from the leaves of Aglaia exima

Cabraleahy­droxy­lactone, C(27)H(44)O(3), isolated from the leaves of Aglaia exima, has three six-membered rings fused together that adopt chair conformations. Its two five-membered rings are enveloped shaped. The hy­droxy group is in an axial position. It is a hydrogen-bond donor to the carbonyl O...

description Cabraleahy­droxy­lactone, C(27)H(44)O(3), isolated from the leaves of Aglaia exima, has three six-membered rings fused together that adopt chair conformations. Its two five-membered rings are enveloped shaped. The hy­droxy group is in an axial position. It is a hydrogen-bond donor to the carbonyl O atom of an adjacent mol­ecule; the O—H⋯O inter­actions lead to the formation of a helical chain that runs along the b axis. There are two independent mol­ecules in the asymmetric unit.
