Memory of chirality in triplet 1,7-diradicals was detected for the first time and to a remarkably high degree in the decarboxylative photocyclization of the proline derivative of N-phthaloyl anthranilic acid 1 into 2 (X=H: 45 % yield, 86 % ee; X=Cl: 50 % yield, 79 % ee).
首次检测到三重态1,7-双自由基中的手性记忆,并且在N-邻苯二甲酰邻氨基苯甲酸1的脯氨酸衍生物的脱羧光环化反应中表现出很高的手性记忆力(X = H:45%的收率,86% ee; X = Cl:50%产率,79%ee)。
