7-氮杂-3,6-二氧杂-二环[330]辛-2-酮类化合物合成的新方法

A Novel Synthetic Route to 7-Aza-4-methoxy-3,6-dioxobicyclo[3.3.0]-octen-2-one Derivatives

5 甲氧基 2 ( 5H) 呋喃酮与氮酸硅烷基酯通过 1 ,3 偶极环加成反应可以为 7 氮杂 4 甲氧基 3,6 二氧杂 二环 [3 3 0 ]辛 2 酮类化合物提供新的合成途径。通过元素分析、IR、1HNMR、13CNMR。

In this paper, a novel synthesis of 7 aza 4 methoxy 3,6 dioxo bicyclo[3 3 0] octen 2 one derivatives via 1,3 dipolar cycloaddition of the 5 alkoxy 2(5H) furanone with silyl nitronates has been investigated. The chemical structures of the new compounds were identified on the basis of their elemental analytical data and spectroscopic data, such as IR, 1H NMR, 13 C NMR and MS.
