Synthesis of Benzopyran-4-Amides Potassium Channel Openers Via Palladium-Catalyzed Amidation
摘要:
The novel potassium channel openers benzopyran-4-amides have been synthesized via palladium-catalyzed amidation of 4-bromobenzopyrans under an atmoshere in the presence of an equivalent of potassium iodide.
A benzopyran derivative represented by general formula (I) and a pharmaceutically acceptable salt thereof, whrein R, X and Y represent together any of the combinations represented by (A). These compounds are excellent in the potassium channel activity and also in safety.
通式(I)代表的苯并吡喃衍生物及其药学上可接受的盐,其中 R、X 和 Y 共同代表(A)所代表的任何组合。这些化合物具有优异的钾通道活性和安全性。
