Photoamination of 2-Alkoxynaphthalenes with Alkylamines via Electron Transfer and Its Application to Synthesis of 1-Alkylamino-2-tetralones

Yamashita, Toshiaki,Tanabe, Kimiko,Yamano, Katsuhiko,Yasuda, Masahide,Shima, Kensuke

, p. 246 - 250 (1994)

Photoamination of 2-alkoxynaphthalenes (1) with ammonia and primary alkylamines were performed by irradiating an acetonitrile-water solution containing 1, an amine, and m-dicyanobenzene to give 1-alkylamino-2-alkoxy-1,4-dihydronaphthalene (2) in relatively good yields.The conversion of 2 to N-acetyl-1-alkylamino-2-tetralones was performed by acetylation with Ac2O by a treatment with BF3*OEt2.
