An efficient gold‐catalyzed oxidation/1,2‐ heteroaryl migration cascade leading to 2‐heteroaryl‐substituted 1,3‐diketones and its further application in the one‐pot synthesis of 4‐heteroaryl‐substituted pyrazoles and the preparation of 4‐heteroaryl‐substituted isoxazoles are reported. A wide variety of 4‐heteroaryl‐substituted pyrazoles were obtained, indicating the broad substrate scope and functional
一种有效的金催化氧化/ 1,2-杂芳基迁移级联反应,产生2-杂芳基取代的1,3-二酮,并将其进一步应用于4-杂芳基取代的吡唑的一锅合成和4-杂芳基的制备中据报道有取代的异恶唑。获得了各种各样的4-杂芳基取代的吡唑,表明该方法具有广泛的底物范围和官能团耐受性。
