    TMOP as a Protecting Group (TMOP = 2,4,6-Timethoxyphenyl)

    Advantages of the 2,4,6-Trimethoxyphenyl Protecting Group:

    • Selective introduction with commercially available reagents
    • Easy to characterize by NMR spectroscopy
    • Is stable under basic, neutral, and oxidative conditions
    • Highly selective cleavage under very mild conditions (0 °C) with simultaneous introduction of a reactive Si–Cl bond
    • The byproduct of the cleavage (1,3,5-trimethoxybenzene) is pH-neutral and relatively inert and can be largely removed by crystallization from unpolar solvents
