| Abstract: | Phosphorylation of β-cyclodextrin with trivalent phosphorus acid diamides in pyridine is found to proceed selectively at primary hydroxy groups under mild conditions (20°C) due to the supramolecular effect of the cyclodextrin cavity. The compounds obtained are of practical interest for further synthesis on their basis of amphiphilic glycophospholipids immobilized on the cyclodextrin matrix. |
