A facile synthesis of Hantzsch 1,4-dihydropyridines with unsymmetrical 2,6- and 3,5-substituents in a one-pot two-step tandem reaction under solvent-free conditions, promoted by microwave irradiation, has been developed. No catalysts are used and the work-up is easy. This approach provides a convenient, efficient and practical synthesis of 1,4-dihydropyridines having non-identical substituents at the
已经开发了一种在无溶剂条件下,通过微波辐射促进的具有不对称 2,6-和 3,5-取代基的 Hantzsch 1,4-二氢吡啶的简便合成,在一锅两步串联反应中。不使用催化剂,后处理很容易。这种方法提供了在 2,6- 和 3,5- 位置具有不同取代基的 1,4-二氢吡啶的方便、有效和实用的合成,这些取代基不容易通过经典 Hantzsch 合成获得。
