ABSTRACT:
A process for manipulating any polyhydroxy compound bearing two or more primary and secondary hydroxyl groups to expose only the primary hydroxyl groups, while blocking all interfering secondary hydroxyl groups as their methyl or other alkyl ethers. More particularly, the present invention relates to the synthesis of 2,3,3',4,4'-penta-O-methylsucrose by using this method.
