Direct irradiation of atropisomeric α-substituted acrylanilides in the presence of alkali metal ions gave high ee values in the 3,4-dihydro-2-quinolin-2-one photoproduct, while in the absence of alkali metal ions, racemic photoproduct was observed. The heavy atom effect leading to enhanced triplet yields alters the reactive pathway leading to the observed enantioselectivity in the photoproduct.
在碱金属离子存在下直接辐照手性α-取代丙烯酰胺，可得到高 ee 值的 3,4-二氢-2-喹啉酮光产物，而在没有碱金属离子的情况下，则观察到外消旋光产物。重原子效应导致三重态产率增加，从而改变了反应途径，导致观察到光产物的对映选择性。
