    Abstract

    The molecule of O-acetylswietenolide, C29H36O9, isolated from the seeds of Swietenia macrophylla, features four six membered rings connected together in the shape of a bowl; one of the inner rings adopts a twisted chair conformation owing to the C C double bond. The furyl substitutent is connected to an outer ring, and it points away from the bowl cavity. The hydroxy group is connected to a carbonyl O atom of an adjacent molecule by an O—H� � �O hydrogen bond, generating a chain running along the b axis.
