Abstract
During the course of our study on the synthesis of new pyridine-C-nucleosides with potential anti-viral and/or anti-tumourai properties, the preparation of 2-carbamoylmethyl-6-β-D-ribofuranosylpyridine 1, by means of a lithiation reaction on 2-(2,3-0-isopropylidene-β D-nbofuranosyl)-6-methylpyridine 2, was investigated (Scheme I). The latter compound was prepared by treating 6-methyl- toluenesulphonic acid. 2-(& D-ribofuranosyl)pyridine 1 2 with 2.2-dimethoxypropane in the presence of p-
