Photochemical Reactions of o-Alkenylphenols and 1-Alkenyl-2-naphthol with Alkylamines: Amination via Photoinduced Proton Transfer

Irradiation of o-alkenylphenols 1a-c and 2a-e in the presence of alkylamines gave o-(1-alkylaminoalkyl)phenols 4a-n and 5a-e in relatively good yields.Deprotonation of these o-alkenylphenols by the amines occurs in the excited singlet state to give the excited singlet state of the phenolate anion 7 and the ammonium ion.The proton transfer from the ammonium ion to the alkenyl group of 7 generates the zwitterion 8 that allows the nucleophilic addition of the amine at the benzylic cation centre.Similar photoamination of 1-(2-methylpropenyl)-2-naphthol 3 with alkylamines occured to give 1-(1-alkylamino-2-methylpropyl)-2-naphthols 6a-b.
