[reaction: see text] An approach to various phosphoramidates has been developed through one-pot chemoselective reaction of nucleoside di- and triphosphates with 3'-amino-3'-deoxythymidine, d-glucosamine, and peptides mediated by trimethylsilyl chloride, and the corresponding conjugates via the linkage of phosphate were obtained. The method could be generally applied for the synthesis of phosphoramidates without any preprotection of polyphosphates and amines containing multifunctional groups.
