A rapid synthesis of oligodeoxyribonucleotides on solid support is described via coupling of the deoxyribonucleoside 3'-H-phosphonates in the presence of various condensing reagents.

A method for the solution-phase synthesis of branched oligonucleotides with tetrahedral or pseudo-octahedral geometry is described that involves the coupling of 3′-H-phosphonates of protected dinucleoside phosphates and organic core molecules. The dimer building blocks are produced by a synthesis that requires no chromatographic purification and that produces the dimer H-phosphonates in up to 44% yield in less than three days of laboratory work. A total of seven different branched hybrids were prepared, including a new hybrid of the sequence (CG)4TBA, where TBA stands for tetrakis(p- hydroxybiphenyl)adamantane that assembles into a material from micromolar aqueous solution upon addition of MgCl2.

Ammonium 4-methylphenyl H-phosphonate 4c was used in the conversion of 5'-0-(dimethoxy-trityl)-2'-deoxynucleoside derivatives 6 into the corresponding 3'-H-phosphonates 2, which were isolated in a high state of purity and in high yield.

Evidence will be presented to show that the monofunctional phosphitylating reagents bis(N,N-di-ethylamino)chlorophosphine and salicylchlorophosphine are very effective for the preparation of 5'-O,N-protected d-nucleoside-3'-hydrogenphosphonates.
