Palladium-Catalyzed Cross-Coupling/Annulation Cascade for Synthesis of 9-Hydroxy and 9-Aminofluorenes.
9‐Hydroxyfluorenes are easily synthesized via a tandem Suzuki/phenolic aldolisation sequence. This process was extended to 9‐aminofluorenes by simply adding various amines as third partners. X‐ray structures and NMR studies confirmed the presence of intermolecular O−H ⋅ ⋅ ⋅ N hydrogen bonding.
