title: Synthesis of new classes of boron-containing nucleotides.
abstract: Four different types of boron-modified nucleotides are reported: P-boranophosphorothioates, P-cyanoboranophosphates, P-boranomethylphosphonates, and P3'-N5'-boranophosphoramidates. Synthesis of dinucleoside borano-phosphorothioates and nucleoside P-borano-P-thiomonophosphates via a lithium sulfide method is described. The Li2S method also provides an alternative way to synthesize phosphorothioates through a dinitrophenyl P(V) phosphotriester precursor. The mechanism of Li2S substitution was investigated.
