Synthesis of Di- and Trivalent Carbohydrate Mimetics with Oxepane Substructure by Employing Copper-Catalyzed [3+2] Cycloadditions of Alkynes with Azido­oxepanes

A series of enantiopure poly(hydroxy)aminooxepanes was converted into the corresponding azidooxepanes by a safe and efficient copper(II)‐catalyzed diazo transfer reaction employing nonafluorobutanesulfonyl azide as nitrogen donor. These azidooxepanes underwent smooth copper(I)‐catalyzed [3+2] cycloa...
