- A New Route to Substituted Pyrimido[5,4-e]-1,2,4-triazine-5,7(1H,6H)-diones and Facile Extension to 5,7(6H,8H) Isomers
[作者:TURBIAK ANJANETTE J; SHOWALTER H D HOLLIS,期刊:Synthesis, 页码:4022-4026 , 文章类型: Article,,卷期:2009年-23]
- A new route to substituted pyrimido[5,4-e]-1,2,4-triazine-5,7(1H,6H)-diones is outlined. The synthesis proceeds via preformed hydrazone intermediates, which are then condensed with all activated chlorouracil to build up ...
