Abstract
A novel and efficient tandem protocol for the swift synthesis of dihydrobenzo[a]indenocarbazole frameworks from 2-alkynylanilines and 2-alkynylbenzaldehydes via BF3·OEt2-facilitated benzannulation and Friedel-Crafts reaction has been described. This innovative approach accommodates a wide array of functional groups, offering a myriad of diversified carbazole products. Later, postsynthetic modification leads to its C(sp3)-H hydroxylation. Furthermore, the photophysical properties of some selected synthesized moieties have been meticulously investigated, promising exciting avenues for further exploration.
