Phenoxazine関連化合物の研究(第8報)3-(β-Bromopropionyl)-1,2-dihydro-3H-pyrazino[3,2,1-kl]phenoxazineのアルミナーカラムクロマトグラフィーによる3-Acryl-1,2-dihydro-3H-pyrazino[3,2,1-kl]Phenoxazineの生成について

抄録

Columnchromatography of 3-(β-bromopropionyl)-1, 2-dihydro-3H-pyrazino [3, 2, 1-kl]-phenoxazine (III) over alumina in benzene gave 3-acryl-1, 2-dihydro-3H-pyrazino [3, 2, 1-kl]-phenoxazine (VII). Catalytic hydrogenation of VII over Adams'catalyst afforded 3-propionyl-1, 2-dihydro-3H-pyrazino [3, 2, 1-kl] phenoxazine (VIII), which had been obtained by the reaction of 1, 2-dihydro-3H-pyrazino [3, 2, 1-kl] phenoxazine (II) and propionyl chloride.
