Method for preparing nucleotides and related analogues by synthesis on soluble substrate, and biological tools thus prepared
First Claim
1. A method for preparing a modified nucleotide or nucleotide analogue monomer comprising the following steps:
- (1) coupling (i) a soluble polyethylene glycol support with a molecular weight in the range 3000 to 6000 provided with at least one acid, diacid or ether-acid linker and (ii) a nucleoside or nucleoside analogue monomer at an exocyclic amine or hydroxyl group of the nucleoside or nucleoside analogue, using a coupling agent;
(2) phosphorylating said nucleoside or nucleoside analogue coupled to said support with a phosphorylation agent; and
(3) treating said phosphorylated nucleoside or nucleotide analogue coupled to said support so as to prepare the modified nucleotide or nucleotide analogue monomer.

Abstract
The invention concerns a method for preparing monomer nucleotides or nucleotide analogues comprising the steps of: (1) coupling a soluble polyethylene glycol support provided with at least one diacid or ether-acid linker and a monomer nucleoside or nucleoside analogue to an amine group or hydroxyl group of the nucleoside with the aid of a coupling agent; (2) at least one step for phosphorylation of said nucleoside or nucleoside analogue coupled to said support with a phosphorylation agent; (3) cleavage of said support and recovery of at least one monomer nucleotide or nucleotide analogue. The nucleotides prepared are biological tools.
