Looking at its name, the word "spiro" indicates that this is a spiro-ring compound. The so-called spiro ring is that the two rings share one atom. Here "spiro [cyclopento [b] pyridine-6,3-pyrrolido [2,3-b] pyridine]" indicates that this compound is composed of cyclopento [b] pyridine and pyrrolido [2,3-b] pyridine. Two parts are connected by spiro atoms. Among them, cyclopento [b] pyridine and pyrrolido [2,3-b] pyridine form rings and are connected at spiro atoms. The configuration of the chiral center of
" (S) " is S-type. Chiral, like human hands, although similar but cannot overlap. There are chiral centers in this compound, which are determined to be S-configuration according to specific rules.
"2-oxo" means that there is a carbonyl group (C = O) at position 2 in the molecule. Carbonyl is a common functional group in organic compounds and has unique chemical properties.
"1,2,5,7-tetrahydro" indicates that on the carbon atoms at positions 1, 2, 5, and 7, the original double bond or triple bond is added by the hydrogen atom to form a saturated carbon-carbon single bond structure.
"-3-carboxylic acid" indicates that at position 3 of the spiral ring structure, a carboxyl group (-COOH) is connected. Carboxyl groups are also common functional groups, acidic, and can participate in many chemical reactions.
In summary, the structure of this compound consists of a helical ring structure as the core, containing a specific chiral center, and functional groups such as carbonyl, carboxyl, and hydrogenated carbon-carbon bonds at specific positions, which combine with each other to form its unique chemical structure.

(2S) -2-oxo-1,2,5,7-tetrahydrospiro [cyclopento [b] pyridine-6,3-pyrrolo [2,3-b] pyridine] -3-carboxylic acid, this is an organic compound. Looking at its structure, the unique structure of the spiral ring system endows it with other physical properties.
First of all, its solubility is due to the fact that there are both polar carboxyl groups in the molecule and non-polar cyclic structures. Polar carboxyl groups can form hydrogen bonds with water, but non-polar cyclic structures prevent them from dissolving in water. Therefore, its solubility in water should be limited, or slightly soluble in water. In polar organic solvents such as methanol and ethanol, the solubility may be improved due to the formation of hydrogen bonds or similar polarity with the solvent; in non-polar organic solvents such as n-hexane, because the non-polar part is not enough to interact with the solvent, it may be difficult to dissolve.
When it comes to the melting point, in view of the existence of hydrogen bonds between its molecules, especially between carboxyl groups, hydrogen bonds can be formed. To make the molecules break free from each other, more energy is required. Therefore, it is speculated that the melting point should not be low. And the rigid helical structure of the molecule makes the molecular arrangement more regular and tight, which will also promote the increase of the melting boiling point. < Br >
Again, density, because the molecular structure contains polycyclic, atoms are relatively concentrated, the mass is large, and the spatial structure is compact, resulting in an increase in mass per unit volume, so its density or more common small molecule organic compounds are larger.
As for stability, although the helical structure has a certain tension, the interring conjugation effect can compensate the tension energy to a certain extent, so that the whole molecule remains relatively stable. However, the carboxyl group has certain reactivity, and under specific conditions, it may participate in reactions such as esterification and salt formation, which affects its stability.

The synthesis of (S) -2-oxo-1,2,5,7-tetrahydrospiro [cyclopento [b] pyridine-6,3-pyrrolo [2,3-b] pyridine] -3-carboxylic acid is an important topic in the field of organic synthesis. This compound has a unique structure and requires a delicate strategy for synthesis.
To synthesize this compound, you can start by building a key skeleton. First, you can prepare a cyclopento [b] pyridine-containing structural fragment first, and use a suitable pyridine derivative as the starting material, and use nucleophilic substitution or cyclization to build this part of the structure. For example, the halogen atom at a specific position on the pyridine reacts with a nucleophile containing a cyclopentyl group to form a preliminary carbon-carbon bond, and then the cyclopento [b] pyridine structure is obtained by intramolecular cyclization.
Second, the construction of the pyrrolido [2,3-b] pyridine part can be synthesized by means of nitrogen-containing heterocyclic synthesis. The pyrrole derivative is used as a base, condensed with a carbonyl compound, and then cyclized to construct the pyrrolido [2,3-b] pyridine structure. This process requires precise control of the reaction conditions to obtain the desired regioselectivity and stereochemistry.
Subsequently, the two key structural fragments are connected, and transition metal-catalyzed coupling reactions, such as palladium-catalyzed cross-coupling, can be used. During the reaction, careful selection of ligands and bases is required, and the reaction temperature and time are optimized to improve the bonding efficiency and product purity.
