Abstract
The invention provides a method of modifying a phosphomonoester moiety of a target compound. The method can include the steps of (a) providing a target compound having an electrophilic moiety and a phosphomonoester moiety; (b) contacting the target compound with a first carbodiimide compound under conditions for preferential addition of the first carbodiimide compound to the electrophilic moiety over the phosphomonoester moiety, thereby forming an electrophile-protected target compound; and (c) contacting the electrophile-protected target compound with a second carbodiimide compound and a nucleophilic compound under conditions for addition of the nucleophilic compound to the phosphomonoester.
