The enantiomeric ratio (e.r.) in the 3,4-dihydroquinolin-2-one photoproduct during 6π-photocyclization of α-substituted axially chiral ortho-tert-butyl-acrylanilides depends on the nature of the reactive spin state (singlet or triplet), where the singlet-spin state reactivity gives a racemic mixture and the triplet reactivity gives an e.r. value >95 : 5.
在 α-取代轴向手性邻叔丁基丙烯酰胺的 6π-光环化过程中，3,4-二氢喹啉-2-酮光产物的对映体过量比（e.r.）取决于反应自旋态的性质（单重态或三重态），其中单重态自旋态反应得到外消旋混合物，三重态反应得到 e.r. 值>95:5。
