A simple two-step synthesis of a new class of fluorinated isoxazolidinyl derivatives of pyrimidine is described. The reactions proceed via the Suzuki–Miyaura coupling followed by highly regioselective 1,3-dipolar cycloaddition with nitrones. Removal of the pyrimidine protecting groups leads to a fluorinated isoxazolidine analogue of pseudouridine.
描述了一种新型的嘧啶氟化异恶唑烷基衍生物的简单两步合成方法。该反应通过Suzuki-Miyaura偶联进行,然后与亚硝基进行高度区域选择性的1,3-偶极环加成反应。嘧啶保护基的去除导致假尿苷的氟化异恶唑烷类似物。
