- N-Nitroso Group-Assisted Nucleophilic Aromatic Substitution of 6-Chloropyrimidines: A Facile and Efficient Synthesis of Pyrimidine-4,6-and-2,4-diamines
[作者:JAKUBKIENE VIRGINIJA; ZURBA JUSTINAS; CIKOTIENE INGA,期刊:Synthesis, 页码:448-451 , 文章类型: Article,,卷期:2013年45-4]
- An N-nitroso group was used to activate chloropyrimidines toward nucleophilic substitution by amines. This permitted a simple, one-pot, high-yielding synthesis of pyrimidine-4,6- and -2,4-diamines.
- Water-Dependent Reduction of Carbohydrate Azides by Dithiothreitol
