that control their quantum-efficient transformation into free amines or diamines have been investigated. The basic design involves the protection of amines with photolabile [(o-nitrobenzyl)oxy]carbonyl groups or α-substituted analogues. The resulting protected amines owe their light sensitivity to the classical o-nitrobenzyl photorearrangement and cleanly liberate free amine in both the solid state
已经研究了有机碱的新型光前体的设计以及控制其量子效率转化为游离胺或二胺的空间和电子因素。基本设计涉及用光不稳定 [(o-nitrobenzyl)oxy] 羰基或 α-取代类似物保护胺。所得受保护的胺的光敏感性归功于经典的邻硝基苄基光重排,并且在用低于 400 nm 的紫外光照射时,可以在固态和溶液中干净地释放游离胺。探索了几种设计,其中光活性中心的结构有系统地变化,以研究各种空间和电子效应的影响。在所有情况下,
