A C-H bond of electron-rich heterocycles is transformed into a C-N bond in a reaction sequence comprising the formation of heteroaryl(phenyl)iodonium azides and their in situ regioselective fragmentation to heteroaryl azides. A Cu(I) catalyst ensures complete regiocontrol in the fragmentation step and catalyzes the subsequent 1,3-dipolar cycloaddition of the formed azido heterocycles with acetylenes. The heteroaryl azides can also be conveniently reduced to heteroarylamines by aqueous ammonium sulfide. The overall C-H to C-N transformation is a mild and operationally simple one-pot sequential multistep process.
Synthesis of distamycin a polyamides targeting G-quadruplex DNA

A number of amide-linked oligopyrroles based on distamycin molecules have been synthesized by solid-state methods, and their interactions with a human intramolecular G-quadruplex have been measured by a melting procedure. Several of these molecules show an enhanced ratio of quadruplex vs. duplex DNA binding compared to distamycin itself, including one with a 2,5-disubstituted pyrrole group. Quadruplex affinity increases with the number of pyrrole groups, and it is suggested that this is consistent with a mixed groove/G-quartet stacking binding mode. The Royal Society of Chemistry 2006.

, (2008/06/13)
Novel pharmaceutically/cosmetically-active polyaromatic amides have the structural formula (I): STR1 wherein Z is a radical --CO--NH-- or --NH--CO--, and are useful for the treatment of a wide variety of disease states, whether human or veterinary, for example dermatological, rheumatic, respiratory, cardiovascular and ophthalmological disorders, as well as for the treatment of mammalian skin and hair conditions/disorders.
