Cycloaddition Reactions of Azatrienes with Sulfene
Abstract: Unprecedented cycloaddition reactions of azatrienes (1) with sulfene leading to the synthesis of functionalized thiazinedioxide derivatives (5) are described. The reactions were found be highly regioselective resulting in the formation of only [4 + 2] cycloadducts.
