successful example of deacylative annulation of 1,3-diones with sulfoxonium ylides was achieved through Ru(ii)-catalyzed C-C bond activation. The excellent chemoselectivity and broad substrate scope render this method a practical and versatile approach for the preparation of (hetero)aryl and alkenyl substituted furans, which are valuable units in many biologically active compounds and functional materials
通过Ru(ii)催化的CC键活化,实现了第一个成功的1,3-二酮与亚砜基酰基化脱酰基反应的成功例子。出色的化学选择性和广泛的底物范围使该方法成为制备(杂)芳基和烯基取代的呋喃的实用且通用的方法,这是许多生物活性化合物和功能材料中的重要单元。初步的机理研究表明,该过程涉及脱酰基α-钌基化反应,以生成关键的烷基Ru(ii)中间体,并释放出苯甲酸片段。
