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.

Supporting information


Comment top

The Aglaia genus consists of some 130 species of trees and shrubs distributed mainly in the tropical rain forests of Southeast Asia. Cabraleahydroxylactone (Scheme I) has been isolated from Aglaia crassinervia (Su et al., 2006) and Aglaia perviridis (Yang et al., 2008) as well as from other plants, and the structure and absolute configuration have been established from spectroscopic measurements. The structural assignment is confirmed by the present crystal structure analysis of the compound isolated from Aglaia exima. There are two independent cabraleahydroxylactone molecules in the asymmetric unit. Each molecule has three six-membered rings fused together that adopt chair conformations. The two five-membered rings are enveloped-shaped (Figs. 1 and 2). The hydroxy unit is axial; this unit is hydrogen-bond donor to the double-bond oxygen atom of an adjacent molecule. The O–H···O interactions lead to the formation of a chain that runs along the longest axis of the orthorhombic unit cell.

Experimental top

The leaves of Algaia exima were collected from Kampung Kepayang, Pahang, Malaysia. The leaves (1 kg) were soaked in n-hexane for 4 days. The solution was decanted and then evaporated to leave a residue of 25 g; a 15 g portion was subjected to column chromatography over silica gel at a gradient mixture of n-hexane and ethyl acetate. Of the 123 fractions, fractions 94–100 were separated by column chromatography (7:3 n-hexane:ethyl acetate) to give a colorless solid. Single crystals of cabraleahydroxylactone were obtained by recrystallization from ethyl acetate.

Refinement top

Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 to 1.00 Å, U(H) 1.2 to 1.5U(C)] and were included in the refinement in the riding model approximation. The torsion angles of the methyl groups were refined. The hydroxy H-atoms were similarly placed [O–H 0.84 Å] and their displacement parameters were set to 1.5U(O).

3940 Friedel pairs were merged.
