series of 8-(1H-1,2,3-triazol-4-yl)-substituted adenosine derivatives have been synthesised by using Sonogashira cross-coupling and click chemistry. The use of click chemistry enables an easy access to different substituents in the 4-position of the triazole ring. The modified nucleosides show high absorptivities due to a single strongly allowed electronic transition and, for some of the derivatives, high
通过使用 Sonogashira 交叉偶联和点击化学合成了一系列 8-(1H-1,2,3-triazol-4-yl)-取代的腺苷衍生物。使用点击化学可以轻松获得三唑环 4 位的不同取代基。由于单个强烈允许的电子跃迁,修饰的核苷显示出高吸收率,并且对于某些衍生物,在有机和水溶液中的高量子产率使它们有希望作为核酸环境中的荧光探针。此外,1,2,3-三唑的不同取代基使发射波长可调,而不会显着改变吸收特性。((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
