title: A solid supported reagent for internucleoside H-phosphonate linkage formation.
abstract: A fast and convenient procedure for synthesis of dinucleoside H-phosphonates is obtained through use of the novel polystyrene supported 5-carboxy-5-methyl-2-oxo-2-chloro-1,3,2-diaoxaphosphorinane reagent. Virtually quantitative H-phosphonate condensations are obtained leading to excellent isolatedyields and with only a simple filtration as the purification procedure. This provides for a convenient and high-yielding procedure that should be suited for solution-phase synthesis of oligonucleotides.
