探索了一种碱催化下单-1-取代的1,2,3-三唑的选择性氢-氘交换反应. 以t-BuOK, t-BuONa或Cs2CO3作为碱, 单-1-取代的1,2,3-三唑在二甲基亚砜(DMSO)-d6溶液中可以选择性地实现C5位置的氘代. 在相应的反应条件下, 4,5-双氘代1,2,3-三唑在相应的反应条件下进行氘-氢交换, 可以选择性地实现C5位置的去氘代过程, 从而实现C4氘代的1,2,3-三唑化合物的合成. 同时, 三唑环辅助下的苯环上的氢-氘交换过程也被观察到.

An effective and selective deuteration of mono-1-substituted 1,2,3-triazoles using base-catalyzed hydrogen-deuterium exchange is proposed. The H/D exchange was selectively conducted at C5 position of 1,2,3-triazoles with catalytic amount of t-BuOK, t-BuONa or Cs2CO3 in dimethyl sulfoxide DMSO-d6. From corresponding 1,2,3-triazoles via H/D exchange process, 5-deutero and 4-deutero mono-1-substituted 1,2,3-triazoles were given from corresponding 1,2,3-triazoles respectively. In addition, the triazole-induced deuteration on phenyl ring was observed.

Key words: H/D exchange, labeling compounds, mono-1-substituted 1,2,3-triazoles, base-catalysis
