- 論文の詳細を見る
In order to obtain the 11-oxygenated benzo [c] phenanthridines photolyses of the 1,2-dihydroisoquinoline (1), the isocarbostyril (3) and its enol acetates (7) and (8) are examined. The 1,2-dihydroisoquinoline (1) and the isocarbostyril (3) do not give the expected compounds. The enol acetates (7) and (8) afford the 11-acetoxybenzo [c] phenanthridines (10) and (11). On hydrolysis and successive oxidation, 10 affords the quinone (13) which is thought to be an intermediate for synthesis of the chelidonine-like compound.
