Abstract
A series of chalcones and their derivatives have been synthesized. Chalcones, 1-(1,3-benzodioxol-5-yl)-3-(aryl)-prop-2-en-1-ones were prepared by the aldol condensation of 1-(1,3-benzodioxol-5-yl)ethanones and aryl aldehydes. Based-catalyzed condensation of 1-(1,3-benzodioxol-5-yl)-3-(aryl)prop-2-en-1-ones with ethyl acetoacetate yields corresponding ethyl 4-(1,3-benzodioxol-5-yl)-6-(aryl)-2-oxocyclohex-3-ene-1-carboxylates. Some of the synthesized chalcones were reported in the literature; the newly synthesized compounds were characterized by single crystal X-ray studies, IR, 1H-NMR and LCMS mass spectral analysis.
摘要:一系列的查尔酮及其衍生物已经合成。查尔酮,1-(1,3-苯并二氧杂环戊烯-5-基)-3-(芳基)-丙-2-烯-1-酮通过1-(1,3-苯并二氧杂环戊烯-5-基)乙酮和芳基醛的醛缩反应合成。在碱性催化下,1-(1,3-苯并二氧杂环戊烯-5-基)-3-(芳基)丙-2-烯-1-酮与乙酰乙酸乙酯发生缩合反应,生成相应的乙酸乙酯 4-(1,3-苯并二氧杂环戊烯-5-基)-6-(芳基)-2-氧代环己-3-烯-1-羧酸酯。一些合成的查尔酮已在文献中报道;新合成的化合物通过单晶X射线衍射、红外光谱、核磁共振和液相质谱分析进行了表征。
