A three-component synthesis of multisubstituted fluorene derivatives has been developed by devising a rhodium-catalyzed stitching reaction/remote nucleophilic substitution sequence. A variety of nucleophiles can be installed in the second step including both heteroatom and carbon nucleophiles. An efficient synthesis of 5H-benzo­[a]­fluoren-5-ones has also been realized using N-(2-alkynyl)­benzoylpyrrole as the reaction partner through a new reaction pathway.
