undergo N-demethylation processes under photochemical conditions. Tropine, acetyltropine, tropinone, and atropine were cleanly N-demethylated upon treatment with tetraphenylporphin, oxygen, and light. Dextromethorphan also underwent a N-demethylation reaction, but reacted further to afford an imine. In contrast, 14-acyloxycodeinones underwent a photochemically induced tandem N-demethylation acyl migration
观察到某些生物碱在光化学条件下经历了N-去甲基化过程。在用四苯基卟啉,氧气和光处理后,将Tropine,乙酰基托平,肌钙蛋白和阿托品干净地N-去甲基。右美沙芬也进行了N-去甲基化反应,但进一步反应得到亚胺。相反,14-酰氧基可待因酮经历了光化学诱导的串联N-去甲基化酰基迁移。
