    摘要:
    The reaction of 6-hydrazinouracils (1) with 3-aryl-1,1,1-trifluoropropane-2,3-dione monohydrates (2) in refluxing ethanol in the presence of p-toluenesulfonic acid gave regioselectively 3-aryl-4-trifluoromethyl-5,6,7,8-tetrahydropyrimido[4,5-c]pyridazine-5,7-diones (4a-e) in moderate yields. The location of a trifluoromethyl group at the C4 position was elucidated on the basis of the chemical transformation of the derivatives.

    摘要:
    Mg促进的2,2,3,3,3-五氟苯乙酮的还原氟硅烷化反应容易产生α-三氟甲基烯醇甲硅烷基醚,然后与亲电子试剂反应生成各种2-取代的3,3,3-三氟苯乙酮,收率极高。相同的协议适用于3,3,3-三氟苯乙酮的烯醇甲硅烷基醚的制备。氟离子催化的2,3,3,3-四氟-2-三甲基甲硅烷基氧基丙苯酮的1,2-脱甲硅烷基-脱氟反应以良好的收率提供了3,3,3-三氟-1-苯基-1,2-丙二酮。

  • A facile synthesis of fluorine-containing heterocycles - use of 1,1,1-trifluoro-2-alkanones as a convenient synthetic intermediate
    作者:Yasuhiro Kamitori

    日期:2001.5
    3-alkanediones 2 easily obtainable from various aldehyde dialkylhydrazones were reacted with several diamines to afford trifluoromethylquinoxalines 3 and trifluoromethylpyrazines 4 in good yields. With the use of aldehydes and aqueous ammonia instead of diamines, diketones 2 were successfully converted to the corresponding 4-trifluoromethylimidazoles 5 in satisfactory yields.

    vinyl, and alkyl ketones are tolerated, delivering products with ≥95% ee and ≥87:13 syn/anti. This methodology offers rapid access to stereopure bioactive molecules. Furthermore, DFT calculations for three types of Noyori–Ikariya ruthenium catalysts were performed to show their general ability of directing stereoselectivity via the hydrogen bond acceptor SO2 region and CH/π interactions.
