regiospecific [4 + 2] cycloaddition of readily available cyclobutenones and active methylene ketones has been developed. On the basis of this strategy, persubstituted phenols/anilines with up to six different functional groups on the benzene ring were synthesized in a single step. In addition, a series of acridine derivatives were prepared in excellent yield from persubstituted phenols/anilines.
