6-formyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid

The chemical structure of 6-formyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid, according to the ancient classical style of "Tiangong Kaiwu", should be as follows.
This compound contains the structure of a pyridine ring. The pyridine ring is a hexamembered heterocycle with a conjugated π electron system, and the nitrogen atom in the ring gives its unique electron cloud distribution and chemical activity. For 1,2-dihydropyridine, that is, the double bond hydrogenation between the two-position and one-position of the pyridine ring, this change changes the electron cloud density distribution of the ring, and its stability and reactivity are also different from those of pyridine.
In the binary position of the pyridine ring, with an oxygenated group, this is the carbonyl structure (C = O). The carbon-oxygen double bond in the carbonyl group, the carbon is positively charged, the oxygen is negatively charged, and the carbonyl group is electrophilic, which is easy to be attacked by nucleophiles and initiates various reactions.
The hexa position of the six-membered ring is connected to the formyl group (-CHO). The carbon-oxygen double bond in this group is connected to the carbon-hydrogen bond. The carbon is a sp ² hybrid and has a planar structure. Formyl is also an electrophilic group and can participate in many organic reactions, such as nucleophilic addition and redox.
In the three digits of the pyridine ring, there is a carboxyl group (-COOH) attached. The carbonyl group in the carboxyl group is connected to the hydroxyl group. Due to the p-π conjugation effect of hydroxyl oxygen, the carboxyl group is acidic and can be dissociated from hydrogen ions. And the carboxyl group can participate in various reactions such as esterification and amidation.
6-formyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid, derived from the pyridine ring. The formyl group, oxo group and carboxyl group attached to the ring interact with each other, giving this compound unique chemical properties and reactivity. It may have potential application value in organic synthesis, pharmaceutical chemistry and other fields.

The synthesis of 6-formyl-2-oxo-1,2-dihydropyridine-3-carboxylic acids has always been an important topic in organic synthetic chemistry. In the past, there were many wonderful methods for the preparation of this compound.
One method is to use pyridine derivatives as starting materials and convert them to functional groups. First, take a suitable pyridine substrate, apply a specific oxidation reagent, such as a high-valent metal salt or a strong oxidizing peroxide, so that a specific position on the pyridine ring is oxidized, and a carbonyl group is introduced. This step requires fine regulation of the reaction conditions. Temperature, solvent, and proportion of reactants are all about success or failure. Then, through ingenious substitution reactions, formyl groups and carboxyl groups are introduced, during which protection and deprotection strategies are required to ensure that the reaction proceeds according to the expected path, and the yield and selectivity of each step are crucial.
The second method is to construct a pyridine ring through a multi-component reaction and introduce the required functional groups. Select the raw materials containing nitrogen compounds, carbonyl compounds and carboxyl groups or their equivalents, and in the presence of a specific catalyst, through multi-step series reaction, one-step construction of the pyridine ring and its 6-formyl, 2-oxo, 3-carboxylic acid and other functional groups. The advantage of this approach is that the steps are simple, but the activity and selectivity of the catalyst are extremely high, and the reaction conditions need to be precisely optimized to obtain the ideal product.
Third, it can be prepared by ring opening, rearrangement and functionalization from simple cyclic compounds. First, the cyclic substrate is ring-opened to generate an intermediate with a suitable activity check point, and then the molecular skeleton is adjusted by the rearrangement reaction. Finally, formyl, carbonyl and carboxyl are introduced to complete the synthesis of the target compound. In this process, the reaction mechanism of each step is complex, and the reaction process needs to be carefully monitored to achieve the purpose of efficient synthesis.
