    摘要: PNA synthesis using a base-labile amino protecting group Processes are described for preparing PNA oligomers, ##STR1## in which R.sup.0 is hydrogen, alkanoyl, alkoxycarbonyl, cycloalkanoyl, aroyl, heteroaroyl, or a group which favors the intracellular uptake of the oligomer, A and Q are amino acid residues, k and 1 are 0 to 20, n is 1-50, B is a nucleotide base which is customary in nucleotide chemistry, and Q.sup.0 is OH, NH.sub.2, or alkylamino which can be substituted by OH or NH.sub.2. In these processes, the amino acid residues and the structural components ##STR2## in which PG is a base-labile amino protecting group and B' is a nucleotide base which is protected on its exocyclic amino function, are coupled step-wise, in accordance with the solid-phase method, onto a polymeric support which is provided with an anchor group, and, after the construction is complete, the target compounds are cleaved from the polymeric support using a cleaving reagent. Intermediates of the PNA oligomers are also described, as are processes for their preparation.

    摘要: The invention provides compounds and processes for synthesis of peptide nucleic acids (PNA). The compounds include temporary amino protecting groups that are base-labile, and protection groups for the exocyclic amino function of the nucleotide base that is compatible with the base-labile amino protecting group. Cleavage of an oligomer comprising these compounds from a solid support can be achieved using weak or medium strength acids.
