1-N-Ethylpyrrole-2-yl ethanone

1-N-ethylpyrrole-2-ylethyl ketone, this is an organic compound. It has specific chemical properties.
In terms of physical properties, at room temperature, it is mostly liquid, with a certain volatility, and its odor or has a unique aromatic smell. Because the molecular structure contains polar carbonyl and pyrrole rings, it has good solubility in organic solvents, such as common ethanol, ether, etc., can be miscible with it, but the solubility in water is relatively limited, because its molecular polarity is not enough to form a large number of hydrogen bonds with water.
In terms of chemical properties, the carbonyl group of the compound is electrophilic and easily reacts with nucleophiles. For example, under acid-catalyzed conditions, condensation reactions can be carried out with alcohols to generate acetal compounds. The hydrogen atom on the pyrrole ring also has certain activity and can be replaced under appropriate conditions. Because the pyrrole ring is an electron-rich aromatic ring, when encountering electrophilic reagents, electrophilic substitution reactions are prone to occur, and the substitution positions are mostly in the 3-position or 5-position of the pyrrole ring.
In addition, although the ethyl group on the nitrogen atom is relatively stable, it may also change under strong oxidation or strong reduction conditions. For example, under the action of strong oxidants, ethyl may be oxidized to oxygen-containing functional groups such as carboxyl groups; in the environment of strong reducing agents, pyrrole rings may be reduced, causing changes in their aromaticity, which in turn affects the chemical activity and properties of the entire compound.
This compound is widely used in the field of organic synthesis due to its own chemical properties, and can be used as a key intermediate to construct more complex organic molecular structures. It has important research value and application prospects in many fields such as pharmaceutical chemistry and materials science.

The common synthesis methods of 1-N-ethylpyrrole-2-ylethyl ketone are as follows:
First, pyrrole is used as the starting material. Pyrrole first reacts with haloethane under alkaline conditions, such as under the action of strong bases such as sodium hydride, in a suitable organic solvent such as tetrahydrofuran, to form N-ethyl pyrrole. Then, N-ethyl pyrrole and acetyl chloride are acylated by Fu-gram in a solvent such as dichloromethane under the catalyst of Lewis acid, such as aluminum trichloride, to obtain 1-N-ethyl pyrrole-2-yl ethyl ketone. In this process, N-alkylation should pay attention to the amount of base and reaction temperature to prevent overreaction; Fu-gram acylation should pay attention to the anhydrous environment and catalyst activity.
Second, you can start from 2-acetyl pyrrole. In the presence of a weak base such as potassium carbonate, 2-acetyl pyrrole and halogenated ethane are heated and refluxed in a solvent such as acetonitrile to undergo N-alkylation reaction to obtain the target product 1-N-ethyl pyrrole-2-ethyl ketone. This method needs to pay attention to the influence of reaction time and temperature on the selectivity of N-alkylation, and at the same time ensure an appropriate excess of halogenated ethane to improve the yield.
Third, N-ethyl-2-pyrrole formaldehyde is used as the raw material. N-ethyl-2-pyrrole formaldehyde is oxidized to the corresponding carboxylic acid in a solvent such as dichloromethane by a suitable oxidant, such as Days-Martin oxidant (DMP), and then reduced to alcohol by LiAlH. Finally, the alcohol is oxidized to 1-N-ethyl pyrrole-2-ylethyl ketone by an oxidant such as PCC (pyridinium chlorochromate). There are many steps in this route, and each step needs to be carefully controlled. The choice of oxidation and reduction conditions is particularly critical to ensure high conversion and selectivity of each step of the reaction.
