copper‐catalyzed synthesis of dihydro[1,2‐b]indenoindole‐9‐ol and benzofuro[3,2‐b]indolines has been developed, whereby the same starting material is employed for the synthesis of both heterocyclic scaffolds and the selectivity of the product is controlled by switching the choice of metal. Salient features of these cascade reactions include wide‐ranging functional group tolerance, simple reaction conditions
二氢[1,2的钯和铜-催化的合成b ]茚并吲哚-9-醇和苯并呋喃并[3,2- b ]二氢吲哚已经开发,由此被用于两个杂环支架的合成相同的起始材料通过切换金属的选择来控制产品的选择性。这些级联反应的显着特征包括广泛的官能团耐受性,简单的反应条件以及中等至高收率。
