A new strategy for the one‐pot synthesis of polysubstituted benzenes through a N , N ‐dimethyl‐4‐aminopyridine (DMAP)‐catalyzed [4+2] benzannulation from readily prepared 1,3‐bis(sulfonyl)butadienes and γ‐substituted allenoates is described. This method provides a facile, metal‐free and general route to highly substituted benzenes under mild conditions in moderate‐to‐good yields with complete regioselectivity.
