Solid‐Phase synthesis of peptide nucleic acids
Abstract
Peptide nucleic acids (PNA) were synthesized by a modified Merrifield method using several improvements. Activation by O‐(benzotriazol‐1‐yl)‐1,1,3,3‐tetramethyluronium hexafluorophosphate in combination with in situ neutralization of the resin allowed efficient coupling of all four Boc‐protected PNA monomers within 30 min. HPLC analysis of the crude product obtained from a fully automated synthesis of the model PNA oligomer H‐CGGACTAAGTCCATTGC‐Gly‐NH 2, indicated an average yield per synthetic cycle of 97.1%. N1‐benzyloxycarbonyl‐N 6 3‐methylimidazole triflate substantially outperformed acetic anhydride as a capping reagent. The resin‐bound PNAs were successfully cleaved by the ‘low–high’ trifluoromethanesulphonic acid procedure.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
