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 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 کاملNew Carboxylic Acid Amides of the Pyrrole Series: Synthetic Routes and Biological Aspects
Complex II inhibitors play an important role in agrochemical fungicide research and have been known for more than 40 years. With the introduction of ortho-substituted heterocyclic amides, a breakthrough in activity level and spectrum within this class was achieved. In the meantime all major agrochemical companies have entered this field. In this paper, a special complex II subclass, the pyrrole...
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.
متن کاملConversion of 4-oxoproline esters to 4-substituted pyrrole-2-carboxylic acid esters.
The Grignard, Wittig, Tebbe, Horner-Emmons, and Reformatsky reactions of the 4-oxoproline esters gave the corresponding 4-alylated or 4-alkylidenated products, respectively. The products were properly treated with bases to cause aromatization, giving 4-substituted pyrrole-2-carboxylic acid esters such as methyl 4-methylpyrrole-2-carboxylate, which is a trail pheromone of Atta texana.
