2-(3-Bromo-4-methoxyphenyl)acetic acid
The title compound C(9)H(9)BrO(3), was synthesized by the regioselective bromination of 4-meth-oxy-phenyl-acetic acid using bromine in acetic acid in a 84% yield. In the mol-ecular structure, the meth-oxy group is almost coplanar with the phenyl ring within 0.06 Å; the acetic acid substituent is tilted by 78.15 (7)° relative to the ring. The C-C-C angles at the OMe, acetyl and Br substituents a...

The backbone of the title mol-ecule, C(26)H(25)BrN(4)O, is approximately planar: the dihedral angle between the planes of the indoline ring system and the furan ring is 7.68 (14)°. In the crystal, layers lying parallel to (10) occur, with the mol-ecules inter-acting via weak C-H⋯N(cyano) and C-H⋯Br bonds and short N(cyano)⋯Br contacts [3.345 (4) Å].
متن کامل2-(3-Oxocyclohex-1-enylamino)acetic acid
The six-membered ring of the title compound, C(8)H(11)NO(3), adopts an envelope shape with the C atom in the meta position of the carbonyl representing the flap. This atom is disordered over two positions in an 0.865 (6): 0.135 (6) ratio. In the crystal, a two-dimensional supra-molecular network parallel to the ac plane is built up from O-H⋯O and N-H⋯O hydrogen bonds.
متن کامل2-(3-Hydroxybenzylamino)acetic acid
There are two independent 2-(3-hy-droxy-benzyl-amino)-acetic acid mol-ecules, C(9)H(11)NO(3), in the asymmetric unit of the title compound. The dihedral angle between the benzene rings of the two independent mol-ecules is 58.12 (4)°. The crystal packing is stablized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.
متن کامل2-Chloro-3-(4-chlorobenzamido)-1,4-naphthoquinone
The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C(17)H(9)Cl(2)NO(3), while the dihedral angle between the amide group and the 4-chloro-phenyl ring is 21.9 (2)°. The conformation of the N-H and C=O bonds are anti to each other. N-H⋯Cl hydrogen bonds link the mol-ecules into chains in the a-axis direction. In addition, these c...
