A practical, versatile, and efficient method for the palladium-catalyzed direct cyanation of readily available acetanilides with K4[Fe(CN)6] as a safe cyanating agent through C–H bond activation with excellent C2 regioselectivity was developed. This finding represents a new strategy for the synthesis of N-(2-cyanoaryl)acetamides, which are important structural motifs in natural products and pharmaceuticals
开发了一种实用、通用且有效的方法,用于钯催化的容易获得的乙酰苯胺的直接氰化,以 K4[Fe(CN)6] 作为安全的氰化剂,通过 C-H 键活化,具有优异的 C2 区域选择性。这一发现代表了合成 N-(2-氰基芳基)乙酰胺的新策略,N-(2-氰基芳基)乙酰胺是天然产物和药物中的重要结构基序。
