-Dihydrobenzofuro[2,3-c]quinolone () and -dihydrobenzofuro-[3,2-c]quinolone () undergo photorearrangement, characteristic to the benzodihydrofuran system, leading to 3--hydroxyphenylquinolone (). A plausible mechanism involving a cyclopropyl dienone () was discussed.
-二氢苯并呋喃[2,3-c]喹诺酮()和-二氢苯并呋喃- [3,2-c]喹诺酮()经历光重排,这是苯并二氢呋喃系统的特征,导致生成3--羟基苯基喹诺酮()。讨论了涉及环丙基二烯酮的合理机理。
