Herein, we report a cascade strategy towards 9-amino-10-alkynylphenanthrenes, which involves copper(I)-catalyzed reactions of 2’-cyano-biaryl-2-aldehyde N-tosylhydrazones and terminal alkynes in a one-pot manner. In addition, the obtained 9-amino-10-alkynylphenanthrenes could be engaged as π-extending building blocks in the synthesis of 9H- dibenzo[3,4:5,6]borinino[1,2-b]phenanthro-[9,10-e][1,2]azaborinine
在此,我们报告了一种针对 9-氨基-10-炔基菲的级联策略,其中涉及铜(I)催化的 2'-氰基-联芳基-2-醛 N-甲苯磺酰腙和末端炔烃的一锅反应。此外,所获得的9-氨基-10-炔基菲可以作为π-延伸结构单元参与9 H-二苯并[3,4:5,6]borinino[1,2- b ]phenanthro-[9的合成,10- e ][1,2]氮杂硼啉(BNTBA)是一种新型BN嵌入PACs,与其全碳类似物三苯并[f,k,m]四吩( TBA )相比显示出不同的性能。本合成方法从易于获得的商业底物开始,为合成高功能化菲和π延伸BN嵌入PAC提供了一种实用的方法。
