Abstract
A novel and efficient single pot synthetic schemes are disclosed for preparing modified nucleotides, nucleotide analogs, nucleotide polyphosphates, and nucleotide polyphosphate analogs. The novel method is used to prepare nucleotides, nucleotide analogs, nucleotide polyphosphates, and nucleotide polyphosphate analogs having non-persistent or persistent and non-persistent modifications. Novel biomolecular reactions are also disclosed using the novel modified biomolecules disclosed herein.

8. A method for preparing a modified nucleotide comprising the steps of:
-
contacting a biomolecule having a phosphate group and a linker having a reactive site protected by a protecting group and a leaving group capable of being displaced by the phosphate group under displacement reaction conditions to form a phosphate protected linker modified biomolecule, and de-protecting the terminal phosphate protected linker modified biomolecule to form a terminal phosphate reactive linker modified biomolecule. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
