Graphical Abstract

How to lose fluorine: Biologically relevant oxazolidinones 1 were synthesized through the desymmetrization of unactivated aliphatic difluorides by Si-induced catalytic CF bond-cleavage using BSA/CsF (BSA=bis(trimethylsilyl)acetamide). The direct transformation of 2 with isocyanates into 1 by cascade carbamoylation/cyclization, in which cyclization is induced by Na-assisted CF bond activation, was also achieved.
