Pd-catalyzed cascade reaction of N,N-dialkyl-substituted o-alkynylanilines involving an indolization/peri-C–H annulation/N-dealkylation sequence has been developed to construct a cyclopenta-fused acenaphtho[1,2-b]indole (ANI) scaffold. A variety of aromatic hydrocarbons having a peri-C–H bond at the alkynyl terminus, such as naphthalene, phenanthrene, pyrene, and fluoranthene, were employed, affording
已经开发了一种新型 Pd 催化的N , N - 二烷基取代的邻炔基苯胺的级联反应,涉及吲哚化 / peri -C-H 环化 / N -脱烷基化序列,以构建环五稠合苊[1,2- b ]吲哚 (ANI) 支架。多种具有芳香族烃的围在炔末端-C-H键,如萘,菲,芘,荧蒽和,被雇用,得到相应的π扩展ANI衍生物。ANI 分子通过增加 HOMO 和降低 LUMO 显示出相对窄的能隙,这意味着它们在低带隙材料中作为 π 段的潜在应用。
