In our contribution we showcase an application of photochemistry for Late Stage Functionalization (LSF) of amino acids and small peptides in an industrial medicinal chemistry environment. The radical intermediates generated under photochemical conditions from the C‐terminal carboxylates undergo rapid 1,4‐conjugate additions to a variety of Michael acceptors. The studied methodology is applicable to
Design, synthesis and biological evaluation of new oligopyrrole carboxamides linked with tricyclic DNA-intercalators as potential DNA ligands or topoisomerase inhibitors
of the design and synthesis of minor groove binding and intercalating DNA ligands some new oligopyrrole carboxamides were synthesized. These hybrid molecules (combilexins) possess a variable and conformatively flexible spacer at the N-terminal end. As intercalating tricyclic systems acridone, acridine, anthraquinones and in a special case iminostilbene terminate the N-terminal end of the pyrrole chain
We present here an efficient and simple method for the N-alkylation of aromatic cyclic imides employing cesium carbonate as the base in anhydrous N,N-dimethylformamide at low temperatures (20-70 ËC). The employment of microwave irradiation presents noteworthy advantages over conventional heating. The method is compatible with base labile functional groups.
