Synthesis of substituted fluorenes by cascade allenylation, electrocyclization and intramolecular friedel-crafts reaction of 1,3-diene-substituted propargylic alcohols

A concise, one-step synthesis of substituted fluorenes through TiCl 4-promoted cascade allenylation, electrocyclization and intramolecular Friedel-Crafts reaction of 1,3-diene-substituted propargylic alcohols has been developed. An interesting substituent-dependent regioselectivity was observed.

Highly efficient synthesis of polysubstituted fluorene via iron-catalyzed intramolecular Friedel-Crafts alkylation of biaryl alcohols

An efficient and mild Fe(III)-catalyzed intramolecular Friedel-Crafts alkylation of biaryl methanol derivatives has been developed to achieve the substituted fluorene derivatives. The present reaction provides an excellent alternative to published methods
