acetyl-protected sulfur groups is reported. Various protecting groups for the catechol moiety were investigated and protected precursors 14–18 were synthesized. In particular, ethyl orthoformate 17 can be easily and selectively deprotected in mild acidic conditions ruling out the need for a strong Lewis acid like borontribromide. The redox activity of 1 was confirmed by cyclic voltammetric investigations
