O‐methyltransferases in plant biosynthetic pathways. Assignments of NMR peaks in the spectra of hydroxylated and/or methoxylated chalcones can help in identifying novel chalcone derivatives isolated from natural sources by referencing these data against NMR spectra obtained from known chalcones. We report here the syntheses of 20 chalcones and complete assignments of 1H and 13C NMR spectra. Copyright © 2010 John Wiley
查耳酮是类黄酮生物合成的中间体,具有抗菌、抗增殖和抗炎特性。查耳酮含有两个苯环,羟基化和甲氧基化的类似物通常由植物生物合成途径中的羟化酶和 O-甲基转移酶产生。羟基化和/或甲氧基化查耳酮光谱中 NMR 峰的归属可以帮助通过将这些数据与从已知查耳酮获得的 NMR 谱相比较来鉴定从天然来源分离的新型查耳酮衍生物。我们在此报告了 20 种查耳酮的合成以及 1H 和 13C NMR 光谱的完整分配。版权所有 © 2010 John Wiley & Sons, Ltd.
