The titanium(III)-mediated radical arylation of 3-hydroxypyridines was found to proceed with high regioselectivity for the 2-position. Using aryldiazonium chlorides, which were prepared from the corresponding anilines, as aryl radical sources, a range of 3-hydroxy-2-phenylpyridines were obtained in moderate to good yields under simple reaction conditions. Reactions of ortho-carboxylic ester substituted

Through a structure‐based molecular hybridization and bioisosterism approach, a series of novel 2‐(pyridin‐3‐yloxy)acetamide derivatives were designed, synthesized, and evaluated for their anti‐HIV activities in MT‐4 cell cultures. Biological results showed that three compounds (Ia, Ih, and Ij) exhibited moderate inhibitory activities against wild‐type (wt) HIV‐1 strain (IIIB) with EC50 values ranging
homogeneous iridium catalyst, providing a direct access to 2- and 4-substituted piperidin-3-one derivatives with high yields, which are important organic synthetic intermediates and the prevalent structural motifs in pharmaceutical agents. Mild reaction conditions, high chemoselectivity, and easy scalability make this reaction highly practical for the synthesis of piperidin-3-ones.
