paper we describe two new basic conditions for the synthesis of quinoxaline 1,4-dioxide derivatives in moderate to good yields. These conditions, exemplified by the use of K2C03 in acetone or KF/A1203 in the absence of an organic solvent, were reproducible and applicable to the synthesis of 2-(carboethoxy)-3-phenylquinoxaline 1,4-dioxide derivatives substituted in position 4 with electron-donating or
在本文中,我们描述了以中等到良好的产率合成喹喔啉1,4-二氧化物衍生物的两个新的基本条件。这些条件下,通过使用的K例举2 C0 3在丙酮或KF / Al 2 0 3在不存在有机溶剂的,是可再现的并且适用于2-(乙氧羰基)-3-苯基喹喔啉的合成1,4-在4位上被给电子或吸电子基团取代的二氧化碳衍生物。
