    摘要: Methods for the chemical 5' phosphorylation of oligonucleotides. An embodiment of the present invention includes reacting the 5' terminus of an oligonucleotide with a composition represented by the formula: ##STR1## wherein if Y and Z are taken separately, each represent an alkyl, aryl, arylalkyl, cycloalkyl or cycloalkylaryl; or if Y and Z are taken together, Y and Z form an alkyl or alkylene chain with both terminal valence bonds of said chain being attached to the nitrogen atom to which Y and Z are attached; or if Y and Z are taken together, with the nitrogen atom, Y and Z form a nitrogen heterocycle including at least one additional heteroatom selected from the group consisting of nitrogen, oxygen, and sulfur. W and X are selected from the group of functional groups subject to nucleophilic attack or .beta.-elimination and are removed.
