The synthesis of new 'bridged' p-cyclodextrin (p-CD) 'dimers' 7-12 was successfully achieved by two one-pot reactions from p-CD (3) and 6A-azido-6A-deoxy-p-CD (4). The 'phosphine imine' reaction was shown to be a superior approach compared to the Mitsunobu reaction as coupling strategy for the prepa
