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 1-{2-[(2-methoxyphenyl)selanyl]phenyl}-4-phenyl-1H-1,2,3-triazole
In the title compound, C21H17N3OSe, the dihedral angles between the central five-membered ring and the C- and N-bound rings are 17.89 (10) and 42.35 (10)°, respectively, indicating the mol-ecule is twisted. The dihedral angle between the Se-bound rings is 85.36 (10)°. A close intra-molecular Se⋯O contact of 2.8507 (13) Å is noted. In the crystal, C-H⋯O, C-H⋯N and C-H⋯π inter-actions lead to the...
متن کامل2-Phenyl-1H-imidazole
In the title compound, C(9)H(8)N(2), a mirror plane lies perpendicular to the phenyl and imidazole rings and passes through the bridging C-C bond, so that the imidazole ring is disordered over two sites about the mirror plane with the equal site occupancy; the asymmetric unit contains one half-mol-ecule. In the crystal, adjacent mol-ecules are linked via N-H⋯N hydrogen bonds.
متن کاملCrystal structure of 1-(1-methyl-1H-imidazol-2-yl)-4-phenyl-1H-1,2,3-triazole dihydrate.
The title compound, C12H11N5·2H2O, which crystallizes as a dihydrate, was obtained by Cu(I)-catalysed azide-alkyne cyclo-addition from 2-azido-1-methyl-imidazole and phenyl-ethyne. The dihedral angles between the central triazole ring (r.m.s. deviation = 0.004 Å) and the pendant imidazole (r.m.s. deviation = 0.006 Å) and phenyl rings are 12.3 (2) and 2.54 (19)°, respectively. In the crystal, th...
