A new efficient copper-catalyzed intramolecular amination reaction has been developed to readily synthesise a wide variety of multi-substituted 2H-indazole and 1H-pyrazole derivatives from easily accessible starting materials under mild conditions. A highly selective ligand for estrogen receptor β was prepared in three steps by employing this method. The Royal Society of Chemistry 2011.

Telomeric DNA is a potential selective target for cancer therapy since the tumour-associated enzyme telomerase regulates telomere maintenance in most cancer cells. The 3′ single-stranded ends of telomeric DNA can be folded into quadruplex structures by appropriate small molecules. We describe the preparation of a new class of 2,7-disubstituted 10H-indolo[3,2-b]quinolines with enhanced selectivity for the stabilisation of quadruplex DNA compared to duplex DNA, and also the preparation of a key intermediate for the synthesis of trisubstituted quindolines.
