Tandem Claisen rearrangement/Diels-Alder reaction in ionic liquid

More Information
  • Aim :The tandem Claisen rearrangement/Diels-Alder reaction in ionic liquid was carried out to find better changes for the conversion. Methods :The synthesis started with replaced benzoic acid via acylation,cyclization,demethylation,allylation and then tandem Claisen rearrangement/Diels-Alder reaction in trational solvent and ionic liquid separately. Results :BmimBF4 raised the yield of the target compound and shortened the reaction time compared with the traditional solvent. Conclusion :BmimBF4 can promote the tandem Claisen rearrangement/Diels-Alder reaction.
