An efficient and green synthesis of pyrazolophthalazinyl spirooxindoles using task specific ionic liquid

, 2014
625-630An environmentally benign approach for the synthesis of pyrazolophthalazinyl spirooxindoles has been developed with the help of a task-specific ionic liquid [DBU][AcOH], which plays the dual role of catalyst as well as reaction medium.
