  Peptide-Oligonucleotide Hybrids with N-Acylphosphoramidate Linkages

  摘要：

  The preparation of a peptide-oligonucleotide hybrid with an N-acylphosphoramidate linkage has been carried out by (i) phosphitylation of the C-terminal carboxamide of a protected peptide by reaction with a chloroalkoxy(dialkylamino)phosphine in the presence of a base, (ii) coupling of the resulting N-acylphosphorodiamidite onto an oligonucleotide-resin followed by oxidation, and (iii) deprotection and cleavage under basic conditions. The synthetic method takes advantage of the unprecedented reaction of primary carboxamides with electrophilic P-III species and takes place under mild conditions which are compatible with the stability of both the peptide and the oligonucleotide components.

  Phosphitylation of Primary Carboxamides. Synthesis of Peptide-Oligonucleotide Conjugates with Acylphosphoramidate Linkages

  摘要：

  N-acylphosphoramidates can be obtained from the reaction of phosphitylated primary carboxamides and an alcohol in the presence of an acid catalyst such as tetrazole and subsequent oxidation. The reaction is useful for the preparation of peptide-oligonucleotide conjugates.
