Crystal structure of (-)-(1'R)-1-(2'-hydroxy-1'-phenyl-ethyl)-1H-pyridin-2-one.
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 2,5-dimethyl-3-(2-methylphenylsulfinyl)-1-benzofuran
The title compound, C17H16O3S, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the benzo-furan ring system [r.m.s. deviation of 0.013 (1) for A and 0.009 (1) Å for B] and the 2-methyl-phenyl ring is 83.88 (5) for A and 86.94 (5)° for B. In the crystal, the B mol-ecules are linked into a chain along the b-axis direction by C-H⋯O hydrogen ...
متن کاملCrystal structure of 4-bromo-N-(2-bromo-3-nitrobenzyl)-2-nitronaphthalen-1-amine
In the title compound, C17H11Br2N3O4, the dihedral angle between the planes of the naphthalene system and the benzene ring is 52.86 (8)°. The nitro substituent and the attached naphthalene system are almost coplanar [dihedral angle = 5.6 (4)°], probably as a consequence of an intra-molecular N-H⋯O hydrogen bond with the amine group. The nitro substituent attached to the benzene ring is disorder...
متن کاملCrystal structure of 3-(morpholin-4-yl)-1-phenyl-3-(pyridin-2-yl)propan-1-one
In the title compound C18H20N2O2, the morpholine ring adopts a chair conformation with the exocyclic N-C bond in an equatorial orientation. The N atom of the morpholine ring and the C atom of the carbonyl group are in an anti conformation about the central C-C bond [torsion angle = -162.92 (11)°] and the dihedral angle between the planes of the benzene ring and the pyridine ring is 83.30 (5)°. ...

In the title compound, C(20)H(12)BrFO(2)S, the dihedral angles between the mean plane [r.m.s. deviation = 0.006 (2) Å] of the benzofuran fragment and the pendant 4-fluoro-phenyl and phenyl rings are 84.98 (5) and 40.98 (6)°, respectively. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯π inter-actions.
