This thesis presented a rapid, efficient and catalyst-free photochemical reaction using a integrated continuous flow system-microreactors to synthesize the pyrrole[3,2-c]quinoline derivatives by the reaction of dialkylanilines and maleimides under the UV light. The use of maleimide and aniline as starting materials with 1,4-dioxane as solvent in ultraviolet light with a wavelength of 252 nm to present the reaction. In addition, the reaction time was reduced from hours to 10 minutes, and successfully synthesized high yields of various pyrroloquinoline derivatives.
