  Fluorescein Analogues as Photoremovable Protecting Groups Absorbing at ∼520 nm

  摘要：

  A new photoremovable protecting group, (6-hydroxy-3-oxo-3H-xanthen-9-yl)methyl (1), with a molar absorption coefficient e of similar to 4 x 10(4) m(-1) cm(-1) at similar to 520 nm for the release of carboxylates or phosphates is reported. Three derivatives of 1 (diethyl phosphate, acetate, and bromide) were isolated as complexes with DDQ and shown to release the ligands with quantum yields <= 2.4% in aqueous solution.
