• Application of Ball Milling Technology to Carbohydrate

    2008-7-24 · Dry ball milling of hexosides with trityl chloride in the presence of DABCO or Na2CO3 has been found to result in their complete conversion to the respective 6‐O‐trityl ethers. Further wet grinding of the reaction mixture with Ac2O in the presence of DMAP led to the respective fully protected hexosides in good to excellent yields after isolation.
