以西佛碱水解法所制得的3-氨基香豆素为原料,通过酰化反应设计合成了3种新的香豆素衍生物N-(3-香豆素基)甲基丙烯酰胺、2-氯-N-(3-香豆素基)乙酰胺和2-溴-2-甲基-N-(3-香豆素基)丙酰胺。经1HNMR、MS和FT-IR证实了它们的结构和组成,并对产物的合成和分离纯化进行了讨论。
3-Aminocoumarin obtained from the hydrolysis of the western feldsine was used as the starting material to synthesize 3 new coumarin derivatives N- (3-coumarin) -methacrylamide and 2 -chloro-N- (3-coumarinyl) acetamide and 2-bromo-2-methyl-N- (3-coumarinyl) propanamide. Their structures and compositions were confirmed by 1HNMR, MS and FT-IR. The synthesis and isolation and purification of the products were also discussed.
