Two new o-hydroxycinnamates have been prepared for photoremovable protecting groups, and their photochemistry has been investigated. The photolysis of two caged compounds can efficiently release the corresponding alcohol in aqueous solutions, and the uncaging reaction proceeds with large one-photon excitation cross sections (1919 and 1535 M(-1) cm(-1)). The uncaging process has been observed by NMR spectroscopy. The caged compounds exhibit good aqueous solubility and excellent resistance to hydrolysis in a buffer solution.
已经制备了两种新的邻-羟基肉桂酸酯作为光解保护基团,并研究了它们的光化学性质。两种笼状化合物的光解可以在水溶液中有效地释放相应的醇,并且光解反应具有较大的单光子激发截面(1919 和 1535 M(-1) cm(-1))。通过 NMR 光谱观察到了脱笼过程。笼状化合物具有良好的水溶性和在缓冲溶液中对水解的优异抗性。
