xy]coumarin ( 1 ) and 7-[2-( N,N -diisopropylamino)ethoxy]-4-methylcoumarin ( 2 ) were synthesized in a traditional way and by microwave-assisted synthesis. The solid state structure was analyzed using X-ray diffraction and 13 C CP/MAS NMR methods. Double resonances were observed in the spectrum of 2 , in contrary to the spectrum of 1 . The X-ray diffraction results indicate that the compound 2 crystallizes
摘要 采用传统方法和微波合成了7-[2-(N,N-二异丙基氨基)乙氧基]香豆素(1)和7-[2-(N,N-二异丙基氨基)乙氧基]-4-甲基香豆素(2)。 -辅助合成。使用X-射线衍射和13 C CP/MAS NMR方法分析固态结构。在 2 的光谱中观察到双共振,与 1 的光谱相反。X射线衍射结果表明,化合物2在单斜空间群P 2 1 / c中结晶,在不对称单元中具有两个分子A和B。
