Crystal structure of ethyl 2-chloro-6-methylquinoline-3-carboxylate
In the title compound, C13H12ClNO2, the dihedral angle between the planes of the quinoline ring system (r.m.s. deviation = 0.029 Å) and the ester group is 54.97 (6)°. The C-O-C-Cm (m = meth-yl) torsion angle is -140.62 (16)°. In the crystal, mol-ecules inter-act via aromatic π-π stacking [shortest centroid-centroid separation = 3.6774 (9) Å] generating (010) sheets.

In the title compound, C14H14ClNO4, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.0142 Å) and ester planes is 18.99 (3)°. The C-O-C-Cm (m = meth-yl) torsion angle is -172.08 (10)°, indicating a trans conformation. In the crystal, the mol-ecules are linked by C-H⋯O and C-H⋯N inter-actions, generating layers lying parallel to (101). Aromatic π-π stacking [centroid-cen...

attracted the attention of chemists, since they exhibit important biological activity in medicinal chemistry.1 As one example, they show very good antibacterial effects.2 Here, we report the crystal structure of the title compound, shown in Fig. 1. To a solution of 1.042 g (10 mmol) of N-ethyl thiourea in 50 mL of absolute ethanol, a solution of 2.645 g (10 mmol) of 1-mesityl-1-methyl-3-(2-chrl...

wide interest because the 1H-pyridin-2-ones obtained in this process are versatile synthetic building blocks in the synthesis of alkaloids,1–5 although little has been done concerning their use in asymmetric synthesis. This contrasts with the large use of chiral piperidones, which have recently been reported. The synthetic method proceeds first through the addition of the hydroxide anion at pos...
متن کاملCrystal structure of 2-chloro-1-(3-ethyl-2,6-diphenylpiperidin-1-yl)ethanone
In the racemic title compound, C21H24ClNO, the dihedral angle between the planes of the benzene rings is 86.52 (14)° and those between the benzene rings and the piperidine ring are 61.66 (14) and 86.39 (14)°. The piperidine ring adopts a twisted boat conformation. No directional inter-actions could be detected in the crystal.
