A facile and efficient copper(I)-catalyzed one-pot, three-component diastereoselective synthesis that provides new 3-spiroazetidinimine-2-oxindoles in excellent yield has been accomplished. The 3-spiroazetidinimine-2-oxindoles underwent a facile ring-opening reaction of the spiroazetidinimine unit by treatment with KOH/MeOH and p-thiocresol under basic conditions to afford two new classes of fluorescent conjugated indolones. This method has general applications with regard to the imines that are derived from 9-fluorenone, 1,2-diketones, and 1,2,3-triketones.
