The structure of osthole has been modified to improve its larvicidal activity against mosquitoes. A new efficient synthesis of osthole derivatives with Grignard reagents has been developed, which employs CuI and LiCl as promoters and covers a broad range of substrates to afford the corresponding products in mild to good yields (up to 83%). Bio‐activity evaluation showed that several products exhibited
修饰了臭虫的结构,以改善其对蚊子的杀幼虫活性。已经开发了一种使用格氏试剂的新型高效合成osthole衍生物的方法,该方法利用CuI和LiCl作为促进剂,并覆盖了广泛的底物,从而以中等至良好的收率(高达83%)提供了相应的产品。生物活性评估表明,几种产品表现出的活性比蛇窝更好。
