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-dipolarcycloaddition with nitrones. Removal of the pyrimidine protecting groups leads to a fluorinated isoxazolidine analogue of pseudouridine.
