Cabraleahydroxylactone from the leaves of Aglaia exima
Cabraleahydroxylactone, C27H44O3, 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 a...

Summary: | Cabraleahydroxylactone, C27H44O3, 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. |
