Sumario:The title compound, C(32)H(40)O(10), also known as xyloccensin L [systematic name: (1R,4aR,4bS,5aR,6aR,9R,10S,10aS,10bR,2aR,13R)-1-(furan-3-yl)-6a-hy­droxy-10-(2-meth­oxy-2-oxoeth­yl)-9,10a,12a-trimethyl-3-oxododeca­hydro-1H,3H,5aH-6,9-methano­isochromeno[6,5-f]oxireno[g]chromen-13-yl (2E)-2-methyl­but-2-enoate], is a limonoid with a C1—C29 oxygen bridge: this is the first report of the X-ray crystal structure of such a limonoid. Two fused pyran rings and two cyclo­hexane rings adopt boat conformations, while another cyclo­hexane ring and the d-lactone ring are in half-chair conformations. The mol­ecular structure is stabilized by intra­molecular O—H⋯O hydrogen bonding.
