Synthesis of 9-Substituted Fluorenols and Heteroring-fused Analogues by Intramolecular C-H Functionalization
A method for the selective synthesis of 9-substituted fluorenols (FOLs) was developed by suppressing intermolecular cyclization and promoting intramolecular C-H functionalization. This protocol was applied to the synthesis of heteroring-fused FOLs. Further, the obtained FOLs were converted to fulvenes by dehydration.
