The synthesis of neoflavene and neoflavenes with methoxy substituents at different positions are described. As starting materials, various salicylaldehydes were run through sequential reactions such as O-allylation, Grignard reaction, oxidation, Wittig reaction, and ring-closing metathesis to yield the target neoflavenes in good yield. Among the prepared neoflavenes, 7-methoxy-4'-methoxyneoflavene
描述了在不同位置具有甲氧基取代基的新黄酮和新黄酮的合成。以各种水杨醛为起始原料,经过O-烯丙基化、格氏反应、氧化、维蒂希反应和闭环复分解等顺序反应,以良好的收率得到目标新黄酮。在制备的新黄酮中,7-甲氧基-4'-甲氧基新黄酮(6e)和8-甲氧基-4'-甲氧基新黄酮(6f)对各种细胞表现出潜在的细胞毒性。特别是,发现6f在体外对胃癌和肺癌细胞的IC 50 值分别为6.5±2.0和5.1±1.1uM。同时,进一步简要讨论了我们合成的新黄酮的结构和活性关系。
