Crystal structure of 3-(2-bromophenylsulfonyl)-2,5,7-trimethyl-1-benzofuran
In the title compound, C17H15BrO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.016 (2) Å] and the 2-bromo-phenyl ring is 82.93 (6)°. In the crystal, mol-ecules are linked via pairs of C-H⋯π hydrogen bonds and π-π inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.881 (2) Å] into inversion-r...
متن کاملCrystal structure of 2-(4-tert-butylphenyl)-3-hydroxy-4H-chromen-4-one
Yellow-green fluorescent crystals of the title compound, C19H18O3, were obtained by the reaction of hy-droxy-aceto-phenone and 4-tert-butyl-benzaldehyde with hydrogen peroxide as oxidant. The plane of the benzene ring is slightly twisted to the mean plane of the 4H-chromene-4-one moiety (r.m.s. deviation = 0.0191 Å) by 10.53 (8)°. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen...
متن کاملCrystal structure of (2S/2R,3S/3R)-3-hydroxy-2-phenylchroman-4-one
In the title mol-ecule, C15H12O3, the C atoms bearing the hy-droxy group and the phenyl ring are disordered over two sets of sites with refined occupancies of 0.573 (7) and 0.427 (7). There is also disorder of the phenyl ring but the hy-droxy group was refined as ordered. The dihedral angles between the benzene ring of the chromane ring system and the phenyl ring are 89.7 (2)° for the major com...

wide interest because the 1H-pyridin-2-ones obtained in this process are versatile synthetic building blocks in the synthesis of alkaloids.1–5 The title compound, (–)-(1′R)-1-(2′-hydroxy-1′-phenyl-ethyl)1H-pyridin-2-one II, was prepared by stirring a solution of pyridinium salt, I (4.0 mmol), in water (25 ml) and cooled to 5 ̊C (Scheme 1). A solution of K3Fe(CN)6 (11 eq.) in water (30 ml) was ad...
متن کاملCrystal structure of 3-(4-bromophenylsulfonyl)-2,5,6-trimethyl-1-benzofuran
In the title compound, C17H15BrO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.015 (2) Å] and the 4-bromo-phenyl ring is 89.29 (6)°. In the crystal, mol-ecules are linked into a chain along the b-axis direction by C-H⋯π hydrogen bonds and C-Br⋯π [3.626 (1) Å] inter-actions.
