1,5-hydrogen atomtransfer (1,5-HAT) strategy for the remote C(sp3)–H functionalization reaction, which includes cyanation, oxidation, and etherification under visible-light-induced photochemical conditions. This reaction is achieved using readily available alkyl N-hydroxyphthalimide esters as radical precursors, which can efficiently react with diverse alkynes to form key vinyl radical intermediates

We developed a facile synthetic method for 9-phenyl-7H-benzocycloheptene derivatives from the Baylis-Hillman adducts. Our method involved intramolecular Friedel-Crafts alkenylation reaction of triple bond-tethered methyl cinnamates. (C) 2004 Elsevier Ltd. All rights reserved.
