Modified nucleotides

The current invention concerns new modified nucleotides that are accepted by reverse transcriptases and incorporated in to a growing oligonucleotide but are not accepted by polymerases. Oligonucleotides comprising the new modified nucleotides can be cleaved photolytically. Also embraced is a process for the synthesis of the new modified nucleotides, and their use.

165. Synthesis of 4′-C-acylated thymidines

Two synthetic pathways towards 4′-C-acylthymidines are presented. These modified mononucleosides are precursors of the 2′-deoxyribonucleotide 4′-C-radical. They were converted into their corresponding 3′-O-[(2-cyanoethyl) N,N-diisopropylphosphoramidites]
