Reaction Steps
The product from step 5 was dissolved in dry DMF and cooled to 0° C. Pyridinium dichromate (PDC, 4 molar equiv) was added portion wise and the reaction mixture was stirred at room temperature for 12 h. It was then diluted with EtOAc, washed with saturated aqueous CuSO4, brine, dried over anhydrous Na2SO4 and concentrated in vacuo. Purification by silica gel column chromatography gave the required N-Boc-6-amino-2,5-anhydro-3,4-di-O-benzyl-6-deoxy-D-mannonic acid in 77% yield.
