catalyzed single-step, stereoselective domino synthesis of symmetrically and unsymmetrically all-carbon tetrasubstituted olefin containing oxindoles from readily accessible anilides has been developed. The Pd-BNP catalyst showed a wide range of functional group tolerance that enabled building a library of heteroaromatics. This reusable Pd catalyst reflected its utility in the synthesis of biologically important
已经开发了由萘甲酸稳定的钯纳米粒子(Pd-BNP)的一步合成的立体选择性多米诺骨牌合成方法,该方法由易于获得的苯胺类化合物合成对称和不对称的含氧吲哚的全碳四取代烯烃。Pd-BNP催化剂显示出广泛的官能团耐受性,从而能够建立杂芳烃库。这种可重复使用的Pd催化剂反映了其在合成生物学上重要的AMP活化的蛋白激酶(不含任何金属Pd污染)的实用性。纳米催化剂易于回收并重复使用五次,而粒度或催化活性没有任何明显的损失。
