An asymmetric tertiary carbon center with a tetrafluoroethylene (–CF2CF2–) fragment: Novel construction method and application in a chiral liquid crystalline molecule
-
Add time:08/17/2019 Source:sciencedirect.com
An asymmetric carbon center with a tetrafluoroethylene fragment can be efficiently constructed via a highly enantioselective conjugate addition reaction of various arylboronic acids with β-(bromotetrafluoroethyl)-α,β-unsaturated ketones. This system can be successfully applied to an enantiomerically enriched tetrafluoroethylenated liquid crystalline molecule.
