C1-c5 photochemical cyclization of enediynes.
This study reports a new photochemical cyclization of tetrafluoropyridinyl (TFP)-substituted enediynes that is accompanied with four formal hydrogen-atom abstractions from organic substrates and is mechanistically different from the Bergman cyclization.
