Abstract
Organodifluorine synthons, in conjuction with three-component diastereoselective anion relay chemistry (ARC), permit ready access to diverse difluoromethylene scaffolds. Initiated via [1,2]-addition of an organolithium reagent to a β-difluoromethylene silyl aldehyde, an alkoxide intermediate is formed, which is capable of undergoing a [1,4]-Brook rearrangement to generate a stabilized α-difluoromethylene carbanion, which, upon electrophile capture, affords a three-component adduct. This three component synthetic tactic represents a novel one-pot divergent strategy for the construction of diverse organodifluorine containing compounds.
