Abstract
A new strategy has been designed for the preparation of gem-difluoro-bisarylic derivatives. It starts from easily accessible and reactive gem-difluoro-propargylic intermediates and elaborates the aromatic rings by a Diels-Alder-aromatization sequence. Heterocyclic systems can be also obtained by 1,3 dipolar cycloadditions, affording mixed aromatic/heteroaromatic derivatives with CF2 as a linker. Since this motif is a bioisostere of O and CO, corresponding bisarylic scaffolds could be of use to prepare chemical libraries of fluorinated analogues of bioactive natural products and/or drugs.
