## Abstract Isoquinolinones were brominated using __N__βbromosuccinimide in dimethylformamide at room temperature to give 4βbromoβ3βsubstituted isoquinolinβ1β(2__H__)βones. The reaction of these isoquinolinones with propargyl bromide in the presence of anhydrous potassium carbonate yielded __N__ an
