The synthesis of new nucleosideanalogues is currently of high interest. We report here full details of a study leading to the synthesis of novel isoxazolidinyl analogues of alpha-amino acid nucleosides. Three different synthetic approaches starting from L-serine have been evaluated for the construction of the isoxazolidine ring. These approaches consisted of Michael addition of N-benzylhydroxylamine
