中文摘要：

在乙醇溶液中具有烯醇醚结构的3-乙酰基-4-甲氧基-2-丁烯内酯和3-（1-甲氧基亚乙基）-4-羰基-2-丁内酯与不同的胺类衍生物发生区域选择性加成-消除反应生成一系列新的稳定的烯胺酮结构衍生物.它们的化学结构经1H NMR、（13）C NMR、X射线衍射和高分辨质谱的确证.其中生成的3-（1-胺基亚乙基）-4-氧代-2-丁内酯类化合物存在明显的Z/E两种异构体.同时对制备反应中产生的副产物结构也进行了确证.

英文摘要：

The regioselective addition-elimination of 3-acetyl-4-methoxy-2-butenolide and 3-（1-methoxy ethylidene）furan- 2,4-dione having enol ether with different amines yielded novel stable enaminone derivatives in ethanol solution. Their struc- tures were elucidated by 1H NMR, 13C NMR, HRMS and X-ray diffraction data. Among of them, the Z/E isomers were ob- served for 3-（1-aminoethylidene）-furan-2,4-dione. The structures of byproducts for preparing intermediates and title com- pounds were also characterized.
