  • Iridium-Catalyzed Site-Selective C–H Borylation of 2-Pyridones
    作者:Koji Hirano、Masahiro Miura、Wataru Miura
    DOI:10.1055/s-0036-1588735
    日期:2017.11
    An iridium-catalyzed site-selective C–H borylation of 2-pyridones has been developed. The site selectivity is predominantly controlled by steric factors, and we can access C4, C5, and C6 C–H on the 2-pyridone ring by the judicious choice of ligand and solvent. Subsequent Suzuki–Miyaura cross-coupling of the borylated products also proceeds to form the corresponding arylated pyridones in good overall

  • C-H Trifluoromethylations of 1,3-Dimethyluracil and Reactivity of the Products in C-H Arylations
    作者:Michal Hocek、Miroslava Ćerňová、Radek Pohl、Blanka Klepetářová
    DOI:10.3987/com-14-12958
    日期:——
    Diverse electrophilic, nucleophilic and radical C-H trifluoromethylations of 1,3-dimethyluracil were systematically studied in order to prepare either 5- or 6-(trifluoromethyl)uracil derivatives. Electrophilic reagents led only to dimeric bis-uracil products, whereas the radical trifluoromethylation by CF3SO2Na in presence of t-BuOOH gave 1,3-dimethyl-5-(trifluoromethyl)uracil (2) in good yield. The 6-(trifluoromethyl)uracil derivative 3 was only prepared in low yield and in a mixture with 2 by Ir-catalyzed borylation followed by treatment with the Togni's reagent. Attempted Pd-catalyzed C-H arylations of 2 in the presence of Cs2CO3 gave mixtures of de-trifluoromethylated products, whereas the reaction with 4-iodotoluene in the presence of CsF gave the desired 6-aryl-5-trifluoromethyluracil derivative 8 in moderate yield and the reaction was not general for other aryl halides.
