光诱导的阻转异构体和非手性烯酮转化表现出不同的反应性。使用非手性烯酮甲酰胺观察到光环化产生 3,4-二氢喹啉-2-酮，而阻转异构体烯酮甲酰胺则经历氢提取，产生螺-β-内酰胺。详细的光化学、光物理和理论研究提供了对这种不同反应性和选择性的见解。
Light-induced transformation of atropisomeric and achiral enones displays divergent reactivity. Photocyclization leading to 3,4-dihydroquinolin-2-one was observed with achiral enone carboxamide, whereas the atropisomeric enone carboxamides underwent hydrogen abstraction leading to spiro-β-lactams. Detailed photochemical, photophysical, and theoretical investigations have provided insight into this divergent reactivity and selectivity.
