In the title compound, C(24)H(15)BrO(2)S, the sulfinyl O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane through the naphthofuran fragment. The phenyl ring is nearly perpendicular to the plane of the tricyclic naphthofuran system [81.77 (6)°] and is tilted slightly towards it. The 4-bromo-phenyl ring is(More)
In the title compound, C(15)H(10)BrClO(3)S, the 4-bromo-substituted benzene ring forms a dihedral angle of 72.55 (6)° with the mean plane [mean deviation = 0.008 (2) Å] of the benzofuran ring system. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into chains along [001]. There are also π-π inter-actions between the furan and benzene(More)
The title compound, C(17)H(16)O(3)S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring exhibits a dihedral angle of 81.16 (4)° with the plane of the benzofuran fragment. The crystal structure is stabilized by π-π inter-actions between the furan and benzene rings of neighbouring(More)
In the title compound, C(19)H(12)BrFO(3)S, the 3-fluoro-phenyl ring makes a dihedral angle of 80.85 (5)° with the mean plane [r.m.s. deviation = 0.009 (2)Å] of the naphtho-furan fragment. In the crystal, mol-ecules are linked by slipped π-π inter-actions between the furan and the outer benzene rings of neighbouring mol-ecules [centroid-centroid distance =(More)
In the title compound, C(17)H(15)ClO(2)S, the O atom and the 4-chloro-phenyl group of the 4-chloro-phenyl-sulfinyl substituent are located on opposite sides of the plane through the benzofuran fragment; the 4-chloro-phenyl ring is approximately perpendicular to this plane [dihedral angle = 87.12 (3)°]. In the crystal structure, mol-ecules are linked through(More)
The title compound, C(24)H(15)BrO(2)S·0.5C(6)H(6), crystallizes as a benzene hemisolvate. The O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the naphthofuran fragment, and the phenyl ring is almost perpendicular to the plane of the naphthofuran fragment [83.78 (8)°] and is tilted slightly towards it.

The title compound, C(12)H(11)ClO(4)S, was prepared by the oxidation of methyl 2-(5-chloro-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate with 3-chloro-peroxy-benzoic acid. The O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic π-π(More)
In the title compound, C(17)H(20)O(3)S, the cyclo-hexyl ring adopts a chair conformation. In the crystal, the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further stabilized by weak inter-molecular C-H⋯O hydrogen bonds. In addition, the crystal structure also(More)
In the title compound, C(21)H(13)BrO(4)S·C(6)H(6), the O atom and the phenyl group of the phenyl-sulfinyl substituent are located on opposite sides of the mean plane of the 5,6-methyl-enedioxy-benzofuran fragment; the phenyl ring is almost perpendicular to this plane [83.66 (6)°]. The 4-bromo-phenyl ring is rotated slightly out of the(More)
