AB  - A new and efficient two-step procedure for the preparation of 5,7-disubstituted 5,7-dihydropyrido[2,3-b:6,5-b]diindoles, containing aryl-, benzyl- as well as alkyl-substituents has been developed. This methodology consists of a chemo-selective double Suzuki-Miyaura cross-coupling reaction followed by a fourfold Buchwald-Hartwig amination reaction. UV/VIS absorption and fluorescence measurements have been carried out for a selected series of compounds. The results are summarized and compared with those of the isomeric 5,7-disubstituted 5-7-dihydropyrido[3,2-b:5,6-b]diindoles.

AB  - The article describes the development of Buchwald–Hartwig amination of different bromoflavones with amino acid and peptide derivatives as nitrogen source giving unique structures. The previously observed racemization, which occurred during the synthesis of flavone-amino acid hybrids, was successfully prevented in most cases. The biological assays of these novel structures showed cytotoxic effects on different cancer cell lines.

AB  - Simple and convenient synthesis of 8-bromoflavone was achieved, starting from 2-bromophenol through 3′-bromo-2′-hydroxyacetophenone whose preparation was managed to be solved by optimized Fries rearrangement. The Buchwald–Hartwig reaction of 8-bromoflavone with different type of primary and secondary amines was carried out.

AB  - The Buchwald-Hartwig amination of aryl halides with secondary amines and functionalized aromatic amines catalyzed by solid-supported palladium is reported. The choices of ligand, base and solvent are crucial for the successful coupling. The ami-nation of aromatic iodides, bromides and chlorides can be easily achieved with palladium on charcoal in the presence of a biphenylphosphane-type ligand at 80-110 °C. In addition, the palladium on charcoal catalyst is easily separable after the reaction, and reusable several times with only small activity loss. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
