1H-Pyrrole-2-carboxylic acid
In the title compound, C(5)H(5)NO(2), the pyrrole ring and its carboxyl substituent are close to coplanar, with a dihedral angle of 11.7 (3)° between the planes. In the crystal structure, adjacent mol-ecules are linked by pairs of O-H⋯O hydrogen bonds to form inversion dimers. Additional N-H⋯O hydrogen bonds link these dimers into chains extending along the a axis.
متن کامل4-Bromo-1H-pyrrole-2-carboxylic acid
In the title compound, C(5)H(4)BrNO(2), the non-H atoms of the pyrrole ring and the Br atom are approximately coplanar, with an r.m.s. deviation from the best fit plane of 0.025 (6) Å;. The dihedral angle between the plane of the carb-oxy group and this plane is 14.1 (2)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules together, forming corrugated sheets parallel to the bc plane.
متن کاملConversion of hydroxyproline to pyrrole-2-carboxylic acid.
Although studies on the degradative metabolism of hydroxyproline have revealed that this amino acid is converted at least in part to glutamic acid (I-G), knowledge of the intermediates in this conversion and of other products of hydroxyproline metabolism is not yet complete. In the course of experiments on the metabolism of hydroxyproline, it was observed that incubation of hydroxyproline with ...
متن کامل1H-Pyrrole-2-carbohydrazide
The title compound, C(5)H(7)N(3)O, was obtained by the reaction of ethyl 1H-pyrrol-2-carboxyl-ate and hydrazide hydrate. In the crystal, mol-ecules are linked via inter-molecular N-H⋯N and N-H⋯O hydrogen bonds, forming a supra-molecular grid.
متن کامل3-(1-Ethyl-1H-pyrrole-2-carboxamido)propionic acid monohydrate
The title compound, C(10)H(14)N(2)O(3)·H(2)O, was synthesized by alkyl-ation of methyl 3-(1H-pyrrole-2-carboxamido)-propion-ate with ethyl bromide, followed by saponification and acidification. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules, forming layers parallel to the ac plane.
