A fast and efficient protocol for the generation of substituted 5-arylidene rhodanines in a sequential one-pot two-step process combining the “Holmberg method” and the Knoevenagel condensation under microwave-assisted conditions has been developed. The final compounds 11a−k have been obtained in high yield and purity after a simple precipitation from methanol, making this procedure facile, practical
已经开发了一种快速有效的方法,该方法在微波辅助条件下,通过“霍姆伯格法”和Knoevenagel缩合的顺序一锅式两步法生成取代的5-芳基罗丹宁。从甲醇中简单沉淀后,已以高收率和高纯度获得了最终化合物11a - k,从而使该程序简便,实用且执行迅速。
