1H-pyrrolo[2,3-b]pyridine-3-acetic acid, alpha-oxo-

1H-pyrrolido [2,3-b] pyridine-3-acetic acid, α-oxo-chemical structure of this compound, let me explain in detail.
According to its name, 1H-pyrrolido [2,3-b] pyridine, this is a fused heterocyclic structure. The pyrrole ring and the pyridine ring are fused in a specific [2,3-b] way. The pyridine ring has a six-membered aromatic ring structure containing one nitrogen atom, while the pyrrole ring is a five-membered aromatic ring containing one nitrogen atom. After fusing the two, a unique skeleton is formed.
As for the "-3-acetic acid" part, it is indicated that an acetic acid group is connected at the 3rd position of the heterocyclic ring. This acetic acid group is formed by connecting a methyl group to a carboxyl group, that is, the -CH -2 COOH structure.
Looking at "α-oxo--" again, this means that the hydrogen atom on the α-position carbon atom connected to the acetic acid group is replaced by an oxygen atom to form a carbonyl structure, that is, -CO -. Overall, the chemical structure of this compound is connected to an α-carbonyl-substituted acetate structure at the 3rd position of 1H-pyrrolido [2,3-b] pyridine. In this structure, the atoms are connected by covalent bonds to form a stable spatial framework, in which the conjugated system of aromatic rings endows it with specific electronic properties and chemical activities, and the presence of carboxyl and carbonyl groups also has a significant impact on the physicochemical properties and reactivity of the compound.
