Nucleophilic 5- Endo - Trig cyclization of 3,3-difluoroallylic metal enolates and enamides: Facile synthesis of ring-fluorinated dihydroheteroles

Metal enolates and enamides bearing difluoroallylic moieties underwent nucleophilic 5-endo-trig cyclization, a process considered to be disfavored according to Baldwin's rules. Whereas no C-cyclization was observed in these reactions, O- and N-cyclization proceeded exclusively to afford 5-fluorinated 2-alkylidene-2,3-dihydrofurans and -2,3-dihydropyrroles, respectively.
