  5′-Bis-conjugation of Oligonucleotides by Amidative Oxidation and Click Chemistry

  摘要：

  A pent-4-ynyl tert-butyl N,N-diisopropyl phosphoramidite was coupled at the 5'-end of oligonucleotides to give a phosphite triester linkage, which forms an H-phosphonate diester linkage during treatment with dichloroacetic acid. Then an amidative oxidation with CCl(4) in the presence of an amine and a 1,3-dipolar cycloaddition with an azide under copper(1) catalysis afforded the bis-conjugated oligonucleotides with high efficiency. The introduction of a bromoalkyl group as a precursor of azidoalkyl by amidative oxidation allowed the performance of two selective 1,3-dipolar cycloadditions.
