Cu-catalysed method for the preparation of highly substituted methylenecyclopentanes, through a sequence involving a Michael addition of stabilized enolates to activated enynes followed by an intramolecular carbocupration reaction, is presented. This method was also successfully combined with a Pd-mediated coupling reaction to perform a new three-component reaction through a transmetallation pathway on
介绍了一种用于制备高度取代的亚甲基环戊烷的 Cu 催化方法,该方法涉及稳定的烯醇与活化的烯炔的迈克尔加成,然后是分子内碳化反应。该方法还成功地与 Pd 介导的偶联反应相结合,通过乙烯基铜中间体的金属转移途径进行新的三组分反应。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
