摘要

The synthesis of mono-, di-and trisubstituted gallic acids and their ester with similar or different groups including different acetal and ketals is described. Regioselective bromination on two ortho-positions of methyl gallate, which is very crucial for many organic syntheses, was achieved in high yield and purity. The α-and β-DDB were synthesized in high overall yield and purity from the regioselective bromoderivatives.
