摘要

Peptide nucleic acid (PNA) analogs based on Nα-(thymin-1-ylacetyl) ornithine were previously shown to form triplexes with complementary RNA. In order to obtain optically pure compounds for hybridization experiments, chiral monomers based on D-or L-ornithine, Nδ- Fmoc-Nα-(thymin-1-ylacetyl) ornithine 2 and Nδ-Fmoc-Nα-(uracil-1-ylacetyl) ornithine 3 were synthesized either by a one-step or by a simple three-step procedure starting from ...
