Method for preparing N-(3'-aryl allyl)pyrrole derivatives

The invention relates to a method for preparing N-(3'-aryl allyl)pyrrole derivatives, which mainly comprises the following step of: reacting 3-aromatic (cycle) propenal with 4-acetoxyl-L-proline at the temperature of between 100 and 180DEG C (performing decarboxylation, redox amination and acetic acid removing aromatization) in an organic solvent such as N,N-dimethylformamide or ionic liquid such as 1-butyl-3-methylimidazolium tetrafluoroborate to obtain target objects. The method has the advantages of cheap and readily available raw materials, simple and practicable operation, high yield and the like.
