The 1,3-benzodioxole ring systems in the title compound, C(22)H(22)O(8), are almost planar. The perhydro-furofuranyl system linking them adopts a distorted double-envelope conformation. Supra-molecular aggregation is effected by C-H⋯O, C-H⋯π and π-π [centroid-centroid distance of 3.755 Å, inter-planar distance of 3.633 Å and dihedral angle of 14.6°] inter-actions.

The asymmetric unit of the title hydrazone compound, C(15)H(10)BrClN(2)O(4), contains two independent mol-ecules. The dihedral angles between the benzene rings are 38.7 (3)° in one mol-ecule and 24.3 (3)° in the other. Both mol-ecules exist in trans conformations with respect to the C=N double bonds of the central methyl-idene units. Intra-molecular O-H⋯N contacts are observed in both mol-ecule...
متن کاملNew benzodioxole compounds from the root extract of Astrodaucus persicus
There are many efforts for identification of natural compounds from dietary or medicinal plants. Young roots and aerial parts of A. persicus have been used as food additive or salad vegetable in some parts of Iran. In this study, different fractions of the root extract of A. persicus were subjected for isolation and purification of secondary metabolites. The methanol extract of the roots was fr...
