An efficient iron-catalyzed cross-coupling reaction between alkynyl bromides and Grignard-derived organocuprates has been developed. A series of alkynylarenes were successfully synthesised by starting from different 1-bromoalkynes and Grignard reagents. The methodology was successfully used for the two-step stereoselective synthesis of combretastatins and represents a valid alternative to the classical
炔基溴化物和格氏衍生的有机铜酸盐之间的有效铁催化交叉偶联反应已被开发。以不同的1-溴炔烃和格氏试剂为原料,成功合成了一系列炔基芳烃。该方法已成功用于考布他汀的两步立体选择性合成,并代表了炔基芳烃经典合成的有效替代方法。
