An efficient synthesis of polysubstituted 2H‐pyrrole derivatives via a silica gel‐promoted intermolecular dearomative Michaeladdition of pyrroles with α,β‐unsaturated ketones has been developed. This transformation features environmentally benign promoter, high efficiency, wide substrate scope and mild reaction conditions.
