    • General Procedure for the Synthesis of 1-β-O- Glucuronyl Carbamates and Carbonates: To a stirred solution of glucuronate 1 (1.5 mmol) and N-methyl-morpholine (5 equiv) in dry MeCN (15 mL) under nitrogen at 0°C was added a solution of either isocyanate or chloroformate (1 mmol in 2 mL of MeCN) over a period of 1 h. The reaction mixture was then allowed to warm to r.t. and stirring was continued for 1 h. The solvent was removed under reduced pressure and the resulting crude product subjected to flash column chromatography.
