In the title compound, C20H16O3S, the dihedral angle between the mean planes of the naphtho-furan and 3-methyl-phenyl fragments is 88.56 (2)°. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers. These dimers are linked by π-π inter-actions between the furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.701 (2) Å] into supra-molec...

The title compound, C(30)H(26)O(4), is a dimer of 6,6'-dimethyl-dibenzo[d,f][1,3]dioxepine linked by formation of a C-C bond in the para position with respect to one O atom. The dimer is arranged around an inversion centre. As is usually observed in related compounds, the dibenzo group is twisted, the two benzene rings making a dihedral angle of 41.56 (9)°. The seven-membered ring exhibits a tw...

The title compound, C(14)H(12)ClNO(2), was prepared by refluxing 4-chloro-benzoyl chloride with o-anisidine in CHCl(3).
