Indole‐tethered amino allenynes were chemodivergently cyclized for the controlled preparation of fused polycyclic indoles using gold catalysis. Double cyclization of terminal allenynes afforded hexacyclic 15 H‐indolo[1,2,3‐de]quinolino[3,2,1‐ij]quinoxalines, in which allenynes bearing a substituted alkyne at the terminal end generated 12,13‐dihydro‐7 H‐indolo[3,2‐c]acridines, which are 5‐membered cyclized
使用金催化化学键合吲哚拴系的氨基艾伦炔,以化学方式控制稠合多环吲哚的制备。末端烯丙炔的双环化提供了六环15 H-吲哚[1,2,3- de ] quinolino [3,2,1- ij ]喹喔啉,其中末端带有取代炔烃的烯丙炔生成12,13-二氢- 7 H-吲哚并[3,2- c ] ac啶,为五元环化加合物。进行密度泛函理论计算以揭示反应性的这种差异。
