The synthesis of 6-selenophenyl derivatives of β-1, 3 and β-1, 4 disaccharides has been explored for the purpose of extending our epoxide fluoridolysis methodology to the synthesis of 5-fluoro analogues of N-acetyl isolactosamine (isoLacNAc, lacto-N-biose) and N-acetyl lactosamine (LacNAc) glycosides. Successful synthesis of the C-6 selenium-containing disaccharides was achieved via Lewis acid-mediated donor and acceptor substrates, the ...
