Crystal Structure of Maturin acetate from Psacalium peltatum (Kunth) (matarique)

抄録

Maturin acetate is a furanoeremophilane natural product compound (C₁₈H₁₆O₅) (4-formyl-9-meth-oxy-5-methyl-naphtho[2,3-b]furan-3-yl)methyl acetate (I), was isolated from Psacalium peltatum (Kunth), named matarique. The crystal has a monoclinic system, space group P2₁/c, Z = 4; the unit cell dimensions are: a = 19.205(3)Å, b = 10.356(2)Å, c = 7.695(1)Å, β = 97.236(3)°. The structure is essentially planar; the molecules in the crystal are joined by a weak interaction C-H-O and π-π stacking.
