2,5-Dimethylphenacyl Esters: A Photoremovable Protecting Group for Phosphates and Sulfonic Acids

Original language description

2,5-Dimethylphenacyl phosphoric and sulfonic esters release the corresponding acids upon irradiation in nearly quantitative isolated yields, with quantum yields F = 0.71 and 0.68 in methanol, 0.09 and 0.19 in benzene. In methanol solution the reactions proceed predominantly via the Z-photoenol, the lifetimes of which (20 and 25 microseconds) were determined by laser flash photolysis. The chromophore is proposed as an excellent photoremovable protecting group for use in organic synthesis and biochemistry.
