developed for the synthesis of 6,7‐dihydro‐5H‐pyrimido[4,5‐e][1,4]diazepin‐8(9H)‐one derivatives. The key to construct the pyrimido[4,5‐e][1,4]diazepine core is the intramolecular amidation of N‐((4‐amino‐6‐chloropyrimidin‐5‐yl)methyl)‐substituted amino acid esters. This methodology was validated through the preparation of 13 representative 6,7‐dihydro‐5H‐pyrimido[4,5‐e][1,4]diazepin‐8(9H)‐ones in moderate
一种新方法是为6,7-二氢5的合成开发ħ嘧啶并[4,5- ë ] [1,4]二氮杂-8-(9 ħ) -酮衍生物。构造嘧啶并[4,5- e ] [1,4]二氮杂core核心的关键是N -((4-氨基-6-氯嘧啶-5-5-基)甲基)取代的氨基酸酯的分子内酰胺化作用。这种方法是通过13代表6,7-二氢5的制备验证ħ嘧啶并[4,5- ë ] [1,4]二氮杂-8-(9 ħ) -酮在中度至良好的产率。J.杂环化学。(2011)。
