How do you protect the diol group of tartaric acid?
To protect the diol group of tartaric acid, you can use a protecting group such as a silyl ether, specifically trimethylsilyl (TMS) or tert-butyldimethylsilyl (TBDMS) groups. These groups can be introduced by treating the tartaric acid with a silyl chloride in the presence of a base, which will selectively react with the hydroxyl groups. After the desired reaction is complete, the protecting group can be removed under conditions that do not affect the rest of the molecule, allowing for further functionalization or manipulation of the tartaric acid.
