To prepare 1-amino-1H-pyrrole-2-formonitrile (1H-pyrrole-2-carbonitrile, 1-amino - (9CI)), there are many methods for its synthesis, which will be described in detail today.
One method can be started from pyrrole. First, pyrrole is reacted with a suitable nitrile reagent to introduce cyano at the 2-position of pyrrole. In this step, mild and efficient nitrile conditions are selected to prevent pyrrole ring overreaction or ring opening. Then, pyrrole 1-position is modified by amination. The amination reagent with suitable activity can be found, and the reaction under the appropriate acid-base environment and temperature can make the amino group successfully replace the hydrogen at the 1-position, and the final product can be obtained.
Another method can start with the construction of nitrogen-containing heterocyclic compounds. By multi-step reaction, the pyrrole ring structure is first established, and functional groups that can be converted into cyano and amino groups are reserved at specific positions. For example, suitable halogenated hydrocarbons or other electrophilic reagents are reacted with nitrogen-containing compounds, and cyano and amino groups are gradually introduced through cyclization and functional group conversion. This process requires fine regulation of reaction conditions to ensure the selectivity and yield of each step.
Another method can utilize transition metal catalysis for the reaction. For example, in the coupling reaction catalyzed by palladium, the target product is directly synthesized by the coupling reaction of halogenated pyrrole derivatives with cyano source and amination reagent under the action of palladium catalyst, ligand and base. This method has the advantages of high efficiency and good selectivity, but the cost of catalyst and post-reaction treatment may need to be considered.
There are various methods for synthesizing 1-amino-1H-pyrrole-2-formonitrile, each with its own advantages and disadvantages. In actual synthesis, the appropriate synthesis path should be carefully selected according to factors such as raw material availability, cost, reaction conditions, and purity and yield requirements of the target product.
