A convenient synthetic procedure has been developed to introduce different functional groups at position 3 of 6-amino-1-benzyl- or 6-amino-1-methyluracil based on N 6-[(dimethylamino)methylene] protection. This method allows for the smooth substitution at N-3 even when base-labile or heat sensitive halide reagents are employed.
基于 N 6-[(二甲基氨基)亚甲基]保护,我们开发出了一种简便的合成程序,可在 6-氨基-1-苄基或 6-氨基-1-甲基尿嘧啶的第 3 位引入不同的官能团。即使在使用对碱不敏感或对热敏感的卤化物试剂时,这种方法也能在 N-3 位顺利实现取代。
