were also synthesized through the same reaction between aldehydes (I) and ketone (II). Their complete 1H‐NMR and 13C‐NMR assignments are reported here and more polysubstituted chromenylchalcones synthesized or isolated from the natural sources in the future can be identified on the basis of the NMR data reported here.

合成了几种含有 2H-色烯基团的查耳酮。2H-chromen-3-甲醛 (I) 与甲氧基取代的苯乙酮的 Claisen-Schmidt 缩合得到 (E)-3-(2H-chromen-3-yl)-1-(甲氧基苯基)prop-2-en-1-ones (色基查耳酮,1-7)。其他类型的色烯基查尔酮 (E)-1-(6-甲氧基-2H-色烯-3-基)-3-(甲氧基苯基)丙-2-烯-1-酮 (8-13)甲氧基取代的苯甲醛和 1-(6-甲氧基-2H-色烯-3-基)乙酮 (II)。Dichromenychalcones (14-16) 也通过醛 (I) 和酮 (II) 之间的相同反应合成。此处报告了它们完整的 1H-NMR 和 13C-NMR 归属,未来可以根据此处报告的 NMR 数据确定更多合成或从天然来源中分离的多取代的色基查耳酮。
