Synthesis of Imidazo[2,1-a]isoquinolines from α-Tosyloxyketones and 1-Aminoisoquinoline in Ionic Liquid Solvent

Synthesis of Imidazo[2,1-a]isoquinolines from α-Tosyloxyketones and 1-Aminoisoquinoline in Ionic Liquid Solvent

The room temperature ionic liquid n‐butylpyridinium tetrafluoroborate (BPyBF4) is used as a ‘green’ recyclable alternative to classical molecular solvents for the cyclocondensation of α‐tosyloxyketones with 1‐aminoisoquinoline to prepare imidazo[2,1‐a]isoquinolines in good yields.
