An efficient strategy for one-pot synthesis of a variety of naphthoquinon-1,3-dithiole derivatives has been developed. The combined action of the formal cycloaddition and oxidation reaction of quinones and amines in the presence of CS2 without additional oxidant produced naphthoquinon-1,3-dithiole derivatives in good yields.
