Article Abstract
A bifunctional ionic liquid (IL) [DDQM][HSO] has been designed and explored as a three-way catalyst for the synthesis of 2-phenylquinazolin-4(3)-ones from anthranilamide and benzyl alcohol in 3.5 min incorporating microwave irradiation. Photochemically the reaction proceeds for 4 h at room temperature and thermally for 8 h at 120 °C. Further IL-assisted metal, solvent, and base free in situ oxidation of benzyl alcohols to aldehydes shows its task specificity. The multifunctionality of the IL was reestablished with the synthesis of two Wnt pathway antagonists.

A direct azidomethylation reaction at the sulfur atoms of thiols with -azidomethyldisulfonimides is presented, providing a facile and efficient approach for the synthesis of azidomethylated compounds with broad substrate scope and mild reaction conditions. Under optimized conditions using -azidomethyl-bis(4-trifluoromethylbenzene)sulfonimide as the azidomethyl source, various aliphatic and aromatic thiols furnish the corresponding -azidomethyl compounds in moderate to high yields. The reaction proceeds selectively at the mercapto group, even in substrates bearing polar functional groups.

Hibernation is an elaborate response strategy employed by numerous mammals to survive in cold conditions that involves active suppression of metabolism. Despite the role of mitochondria as energy metabolism centers during hibernation, the adaptive and evolutionary mechanisms of mitochondrial genes in hibernating animals, like hedgehogs in eulipotyphlan species, are not yet fully understood. In this study, we sequenced and assembled mitochondrial genomes of the hibernating four-toed hedgehog () and the non-hibernating Asian house shrew ().

Maintaining a healthy pool of circulating red blood cells (RBCs) is essential for adequate perfusion, as even minor changes in the population can impair oxygen delivery, resulting in serious health complications including tissue ischemia and organ dysfunction. This responsibility largely falls to specialized macrophages in the spleen, known as red pulp macrophages, which efficiently take up and recycle damaged RBCs. However, questions remain regarding how these macrophages are acutely activated to accommodate increased demand.
