An efficient way to generate a series of rigid tetrahedral organic building units from common methane and adamantane precursors is presented. Suzuki-Miyaura and Sonogashira cross-coupling reactions are used to effectively generate these shape-persistent molecular tectons. Especially the Sonogashira reactions employing the readily available tetrahedral alkynes and commercial iodides and bromides are

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
