Abstract

The convenient synthesis of a library of pyrimidine-isoxazoline hybrids in 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6])-water/potassium hydroxide at ambient temperature has been accomplished. The ionic liquid [bmim][PF6], immiscible in water, can be easily recycled for reuse after separation of the products without any noticeable diminution in its activity. The protocol is rapid, the yields are good to excellent, and the method is facile.
