3′,4′‐Dihydroxyflavone reacts with ethyl 2,3‐dibromopropanoate to form the new, substituted 1,4‐benzodioxanes 1. The regioisomers 1a and 1b were separated by crystallization and converted to the amides 2a and 2b for pharmacological testing for spasmolytic activity. The constitutions of 1 and 2 were elucidated by 400 MHz 1H‐NMR spectroscopy. In the spasmolysis test, antagonistic effects towards acetylcholine
3', 4'-二羟基黄酮与 2,3-二溴丙酸乙酯反应形成新的取代的 1,4-苯并二恶烷 1. 区域异构体 1a 和 1b 通过结晶分离并转化为酰胺 2a 和 2b 用于解痉药理学测试活动。通过400 MHz 1 H NMR光谱阐明了1和2的组成。在解痉试验中,研究了对乙酰胆碱、BaCl 2 和组胺的拮抗作用。检测到非特异性解痉活性。
