USE OF NEW PHOSPHONYLATING AND COUPLING AGENTS IN THE SYNTHESIS OF OLIGODEOXYRIBONUCLEOTIDES VIA THE H-PHOSPHONATE APPROACH

Tris(1,1,1,3,3,3-hexafluoro-2-propyl) phosphite was used as a phosphonylating reagent for the preparation of nucleoside 3'-H-phosphonate units.The use of a new coupling reagent, 1,3-dimethyl-2-chloro-imidazolinium chloride (DMCI) for the internucleotidic H-phosphonate bond formation via the H-phosphonate approach is also discussed in detail.

BISPENTAFLUOROPHENYL CARBONATE IN THE SYNTHESIS OF OLIGONUCLEOTIDES BY THE H-PHOSPHONATE METHOD

Key words: oligonucleotide synthesis; H-phosphonate method; condensing reagent.

A NEW AND VERSATILE APPROACH TO THE PREPARATION OF VALUABLE DEOXYNUCLEOSIDE 3'-PHOSPHITE INTERMEDIATES

The easily accessible and crystalline monofunctional phosphitylating reagent bis-(diisopropylamino)chlorophosphine has been used for the synthesis of phosphoramidites and H-phosphonates of d-nucleosides and, also, the formation of 3'-5'-internucleotidic phosphonate bonds.
