Abstract

gem-Difluorohomopropargyl alcohol is a readilyattainable molecular scaffold that provides easy access tofluorinated propargyl-ethers, -esters, and –amides capableof generating structurally diverse fluorinated heterocycles,such as furans, isochromans, isoquinolines and lactams,using cyclization reactions catalyzed mostly by transitionmetals including Ag, Rh, Ru or Pd.
