method for the solution-phasesynthesis of branchedoligonucleotides 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
