摘要:The present invention relates to the synthesis of peptide-oligonucleotide conjugates (POC). More specifically, the invention relates to a novel method for the preparation of peptide-oligonucleotide conjugates, which can be conducted under mild conditions on solid support, can be performed manually or by a synthesizer, can be used to synthesize alternating sequences of peptides and oligonucleotides, and is applicable to the synthesis of a wide variety of peptide-oligonucleotide conjugates constructed from alternate peptide and oligonucleotide blocks.

摘要:The present invention is a one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using a combination of aryl halides, a substrate, and a copper salt as catalyst. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores and explosives.
