Article abstract of DOI:10.1016/S0040-4039(00)61745-8

Bromine-induced oxidative ring contraction of an α-amino-δ-lactone gave a mixture of α-aminotetrahydrofurancarboxylic esters which may allow the preparation of stable amino acid derivatives at the anomeric position of mannofuranose.The synthesis of N-phen
