  An efficient and environmentally benign Cu-mediated method was developed for direct cascade C–H/N–H annulation to construct polyheterocyclic indoloquinoline scaffolds. This method highlights an emerging strategy for transforming inert C–H bonds into versatile functional groups in organic synthesis and provides a new versatile approach for the efficient synthesis of indolo[3,2-c] and [2,3-c]quinoline

  scaffolds in medicinal chemistry, the indole and 1,3,4‐oxadiazole ring systems, gave rise to 2‐arylamino‐5‐(3′‐indolyl)‐1,3,4‐oxadiazoles with IC50 values in the nanomolar range against a panel of tumor cell lines. Preliminary structure–activity relationship studies indicate potential for improved selectivity through further manipulation of the oxadiazole C‐2 and C‐5 positions.
