5'-Halogeno-2',3'-cyclic sulphite isomers in the preparation of 5'-halogeno nucleosides. Synthesis of 5'-deoxyuridine and 5'-deoxy-5-fluorouridine.

When uridine (Ia) is reacted with thionyl chloride in hexamethylphosphoric triamide a mixture of isomeric 5'-chloro-2',3'-sulphites is formed, which can be separated to individual epimers IIa and IIIa, in 45% and 15% yields, respectively. Analogously, crystalline epimers IIb (37%) and...
