1H-pyrrolido [2,3-b] pyridine, 2,3-dihydro-This compound has the following chemical properties:
Its structure contains nitrogen heterocycles, resulting in a certain alkalinity. The pyridine ring fuses with the pyrrole ring, which makes the electron cloud distribution unique and affects the reactivity. The dihydrogen structure part is more stable than the unhydrogenated part because it contains saturated carbon.
From the perspective of nucleophilic reaction, the solitary pair electron of the nitrogen atom can be used as a nucleophilic check point to react with the electrophilic reagent. If it reacts with halogenated hydrocarbons, the halogen atoms in the halogenated hydrocarbons are attracted by the electron cloud and can be connected to the nitrogen atom to form a new carbon-nitrogen bond.
In the electrophilic substitution reaction, due to the nitrogen electron absorption on the pyridine ring, the density of the electron cloud in the adjacent and para-position decreases, and the meta-position is relatively high, and the electrophilic reagent is more likely to attack the meta-position. Although the pyrrole ring is rich in electrons, after fusing with the pyridine ring, the electron cloud distribution changes and the reactivity is also affected.
During the oxidation reaction, the dihydro part is relatively easy to be oxidized, because the saturated carbon-hydrogen bond can be broken under the action of a suitable oxidant to form oxygen-containing compounds, such as hydroxyl-substituted products.
In the reduction reaction, the pyridine ring and pyrrole ring can be further hydrogenated under strong reducing agents to saturate the unsaturated bond Due to its structural properties, this compound can be used as a key intermediate in the field of organic synthesis for the construction of complex nitrogen heterocyclic compounds, which may have potential biological activity in medicinal chemistry.

To prepare 1H-pyrrolido [2,3-b] pyridine-2,3-dihydro, there are various synthesis methods. First, it can be started by suitable pyridine derivatives. First, find a pyridine substrate with a specific substituent, and under suitable reaction conditions, make a specific position on one side of the pyridine ring attack with a nucleophilic reagent, and introduce a group that can be subsequently cyclized. This step requires fine regulation of the reaction temperature, reagent ratio and reaction time to ensure that the nucleophilic substitution occurs accurately.
Next, through ingenious molecular inner ring reactions, pyrrole rings are constructed. This process may require the help of a specific catalyst or a suitable reaction medium to promote cyclization. For example, a certain type of transition metal catalyst is used, under the protection of an inert gas, heated to an appropriate temperature to promote the rearrangement and bonding of atoms in the molecule, and finally the skeleton of 1H-pyrrole [2,3-b] pyridine-2,3-dihydrogen is obtained.
Second, pyrrole derivatives can also be used as starting materials. First, the pyrrole ring is modified to introduce an active group that can be connected to the pyridine ring fragment. Then, the modified pyrrole derivative is reacted with a reagent containing a pyridine structure. This reaction may be of the type of electrophilic substitution, nucleophilic addition, etc., depending on the selected reagent and active group. After carefully designing the reaction path, the two are gradually combined, and then the subsequent steps of reduction and cyclization are followed to obtain the target product.
Furthermore, there is a strategy to use a multi-step tandem reaction. Select a suitable starting material whose molecular structure contains structural fragments that can construct both pyridine and pyrrole rings. By precisely adjusting the reaction conditions, each part of the raw material molecule reacts in sequence, and goes through a series of processes such as addition, elimination, and cyclization. In the same reaction system, the complex structure of 1H-pyrrolio [2,3-b] pyridine-2,3-dihydro is directly constructed without separating the intermediate products. This series reaction method requires a deep understanding of the reaction mechanism and a precise grasp of the timing and conditions of each step of the reaction in order to achieve the purpose of efficient synthesis.

What you are inquiring about is the price range of 1H-pyrrole [2,3-b] pyridine, 2,3-dihydrogen in the market. However, the price of this product is affected by many factors, and it is difficult to determine it suddenly.
First, the source of the goods is related to the price. If it comes from a well-known factory, with excellent craftsmanship and high quality, the price may be high; if it is produced by an ordinary workshop, the quality is slightly inferior, and the price may be lowered.
Second, the state of supply and demand is also the key. If the market has strong demand for this product and the supply is limited, the so-called "rare is expensive", and its price will rise; conversely, if the supply exceeds the demand, the merchant will sell its goods or reduce its price to promote the transaction.
Third, the difference in geography also has an impact. In bustling cities, commerce is active and logistics is convenient, but the cost of rent is also high, and the price may be different from that in remote places.
Fourth, the volume of transactions also affects the price. If you buy in bulk, the merchant may give a certain discount due to the idea of small profits but quick turnover, and the unit price will be reduced; if you buy a small amount, the unit price may be relatively high.
From a comprehensive perspective, if you want to know the exact price range of this thing, you need to consult the merchant, carefully observe the market, compare its advantages and disadvantages, and measure its supply and demand in order to obtain a more accurate price range. However, with the current situation, it is difficult to give an exact number.
