Description
Summary:The title compound [systematic name: (9-methoxy-3,5-dimethyl-5,6-dihydronaphtho[2,3-b]furan-4-yl)methyl 2-methylbut-2-enoate], C21H24O4, was isolated from matarique, or Psacalium peltatum (Kunth). The structure is almost planar. The angeloyloxy group makes an angle of 62.08 (2)° with the furanoeremophilane skeleton. The carbonyl O atom is disordered between two positions with a 76:24 ratio. The molecules in the crystal are joined by very weak C—H—O interactions in the ac plane.
