Abstract
A method for removing an allyl protecting group from an allyl-protected derivative of a biologically relevant amino acid is disclosed. One relevant aspect of the method is the use of soluble organometallic catalyst, such as an organopalladium catalyst. Preferably, soluble tetrakistriphenylphosphine palladium (0) is used. The allyl deprotection method now disclosed is suitable for use on an instrument for automated peptide synthesis. Methods of preparing the soluble organometallic catalyst are also disclosed, as are soluble catalyst compositions.
