In the title compound, C22H23FO3S, the cyclo-pentyl ring adopts an envelope conformation with the flap atom connected to the benzofuran residue. The 4-fluoro-phenyl ring makes a dihedral angle of 43.67 (3)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions, forming a three--dimensional net...

In the title compound, C14H14BrNO5, the ester group is disordered [occupancy ratio 0.52 (2):0.48 (2)]. The major component is nearly coplanar with the benzofuran plane, subtending a dihedral angle of 7.84 (2)°, while the amide group is twisted out of the benzofuran plane making a dihedral angle of 39.69 (2)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, pairs of weak C-H⋯O hyd...

In the title compound, C(16)H(11)FO(4)S, the O atom and the methyl group of the methyl-sulfinyl substituent are located on opposite sides of the mean plane through the 5,6-(methyl-enedi-oxy)benzofuran fragment. The 4-fluoro-phenyl ring is rotated out of the 5,6-(methyl-enedi-oxy)benzofuran plane, making a dihedral angle of 29.90 (6)°. In the crystal structure, both inter-molecular C-H⋯O hydroge...

The title compound, C(18)H(18)O(3)S, was prepared by the oxidation of 2-methyl-3-phenyl-sulfanyl-5-propyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 81.74 (6)° with the plane of the benzofuran fragment. The crystal structure is stabilized by C-H⋯π inter-actions between a methyl H atom and the phenyl ring of the phenyl-sulfonyl substituent from a ne...

In the title compound, C(20)H(20)O(2)S, the cyclo-pentyl ring adopts an envelope conformation with the flap atom connected to the benzofuran residue. The phenyl ring makes a dihedral angle of 32.36 (9)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked through weak C-H⋯O inter-actions. In the cyclo-pentyl ring, two adjacent C atoms are disordered over two set...

In the title compound, C(16)H(12)FIO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment. The 4-fluoro-phenyl ring is rotated slightly out of the benzofuran plane, as indicated by the dihedral angle of 7.43 (6)°. In the crystal structure, pairs of short I⋯O [3.074 (2) Å] contacts link the mol-ecules into cent...

In the title compound, C(18)H(18)O(3)S, the 4-methyl-phenyl ring makes a dihedral angle of 86.35 (3)° with the mean plane [mean deviation = 0.006 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits weak π-π inter-actions between the furan and benzene rings of neighbouring benzofuran systems [centroid...

New fluorescent Na+ indicators, SBFI (short for sodium-binding benzofuran isophthalate) and SBFP (short for sodium-binding benzofuran phthalate) (Minta, A., and Tsien, R. Y. (1989) J. Biol. Chem. 264, 19449-19457), were tested in Jurkat tumor lymphocytes and in REF52 rat embryo fibroblasts. Both dyes could be introduced by direct microinjection. However, when cells were incubated with the tetra...

In the title mol-ecule, C(17)H(15)FO(2)S, the O atom and the 4-fluoro-phenyl group of the 4-fluoro-phenyl-sulfinyl substituent lie on opposite sides of the benzofuran fragment. The mean planes of the benzofuran and 4-fluoro-phenyl fragments form a dihedral angle of 86.07 (4)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, wh...
