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...

| Sumario: | 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. |
