Synthesis of 3′,5′-Dithymidylyl-α-hydroxyphosphonate Dimer Building Blocks for Oligonucleotide Synthesis—A New Pro-oliguncleotide
摘要:
The synthesis of the dimer building blocks 1 and 2 and their introduction into (T)(15)-oligonucleotides is described. The stability against 3'-exonuclease digestion (SVP) as well as the hybridization properties (T-m values) were examined.

The synthesis of 3'-succinyl-CPG bound 3',5'-di-2'-deoxythymidyl-(alpha-hydroxy-2-nitrobenzyl)-phosphonate diester 1 and the 3'-phosphoamidite derivative 2 is descibed. The hydroxyl-groups of the backbone modification were protected with trialkylsilyl groups: TES and TBS. Compounds 1, 2 are suitable blocks for oligonucleotide synthesis.

A fast and convenient procedure for synthesis of dinucleoside H-phosphonates is obtained through use of the novel polystyrene supported 5-carboxy-5-methyl-2-oxo- 2-chloro-1,3,2-dioxaphosphorinane reagent. Virtually quantitative H-phosphonate condensations are obtained leading to excellent isolated yields and with only a simple filtration as the purification procedure. This provides for a convenient and high-yielding procedure that should be suited for solution-phase synthesis of oligonucleotides.
