1,3,6-Trihy­droxy-7-meth­oxy-2,8-bis­(3-methyl­but-2-en­yl)-9H-xanthen-9-one

The title compound (trivial name α-mangostin), C(24)H(26)O(6), isolated from Cratoxylum glaucum, is characterized by a xanthone skeleton of three fused six-membered rings and two 3-methyl­but-2-enyl side chains. The three rings in the structure are nearly coplanar, with an r.m.s. deviation for the t...

description The title compound (trivial name α-mangostin), C(24)H(26)O(6), isolated from Cratoxylum glaucum, is characterized by a xanthone skeleton of three fused six-membered rings and two 3-methyl­but-2-enyl side chains. The three rings in the structure are nearly coplanar, with an r.m.s. deviation for the tricyclic ring system of 0.0014 Å. The two 3-methyl­but-2-enyl side chains are in (+)-synclinal and (-)-anti­clinal conformations. Intra­molecular O—H⋯O and C—H⋯O inter­actions occur. The crystal structure is stabilized by inter­molecular O—H⋯O, C—H⋯O and C—H⋯π inter­actions.
