12-(2-Methoxyphenyl)-9,9-dimethyl-8,9-dihydro-12H-benzo[a]xanthen-11(10H)-one
The title compound, C(26)H(24)O(3), was synthesized via the coupling of 2-methoxy-benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. The pyran ring adopts a boat conformation, while the cyclo-hexenone ring is in an envelope conformation. The 2-methoxy-phenyl ring is almost perpendic-ular to the plane through the four C atoms of the pyran ring [dihedral angle = 88.76 (9)°].

In the xanthenone system of the title compound, C23H20O4, the pyran ring has a maximum deviation of 0.111 (1) Å from planarity and the outer cyclo-hexene ring exhibits a puckered conformation. The three methyl-ene C atoms of the cyclo-hexene ring bonded to the pyran unit are disordered over two sets of sites [occupancies = 0.570 (3) and 0.430 (3)]. In the crystal, mol-ecules are linked by C-H⋯O...

In the title compound, C(23)H(15)ClN(2)O, the fused ring system is planar: the deviation of all the non-H atoms from the plane through all four fused rings is less than 0.31 Å. The plane of the phenyl ring is inclined at 71.78 (5)° to the mean plane of the 1,8-naphthrydine ring system. The crystal structure is devoid of any classical hydrogen bonds but π-π inter-actions are present.

In the title compound, C(20)H(18)O(2), the central six-membered ring adopts a boat conformation and the terminal benzene rings make a dihedral angle of 42.66 (4)° with each other. In the crystal structure, the O-H group forms both an intra- and an inter-molecular O-H⋯O hydrogen bond; the former generates an S(5) ring and the latter leads to inversion-generated R(2) (2)(10) loops. The dimers are...
متن کامل11-(3-Chloro-2-hydroxypropoxy)-2,3,9-trimethoxychromeno[3,4-b]chromen-12(6H)-one
In the title compound, C(22)H(21)ClO(8), the rotenoid core is nearly planar (r.m.s. deviation 0.114 Å), with the largest deviations from the least-squares plane being 0.286 (3) and 0.274 (2) Å. An inter-molecular O-H⋯O hydrogen bond links two mol-ecules into a centrosymmetric dimer having an R(2) (2)(18) ring motif.
