in Pd-catalyzed challenging heteroaryl–heteroaryl Suzuki–Miyaura cross-couplingreactions under aerobic conditions, exhibiting a general and highly efficient protocol for a range of challenging substrates. Additionally, the current protocols were successfully applied to the synthesis of valuable functional small molecules and conjugated mesopolymers. These findings have significant implications for the
For the development of novel antitumor agents, we designed and synthesized 2,6-diaryl-substituted pyridine derivatives bearing three aryl groups, which are the bioisosteres of terpyridine, and evaluated their biological activities. Most of the 18 prepared compounds showed moderate cytotoxicity against several human cancer cell lines. From the structure-activity relationships we may conclude that the number of aryl groups employed would be critical for their biological activities. (c) 2007 Elsevier Masson SAS. All rights reserved.
