Some reactions of nitrone 4 are described, namely the nucleophilic addition of dialkyl phosphites, HOP(OR)2, 5a–c or of diethyl methylphosphonate 8 and the dipolar [2+3] cycloaddition of vinylphosphonate 11. Chemical transformations led to 4-amino-L-fucose derivatives bearing a phosphonate group in the 1α position linked to the pyrrolidine ring through a chain of 0–2 carbon atoms. The target compounds
