Optimization of a Solid-Phase Synthesis of a PNA Monomer
摘要:
[GRAPHICS]A new scheme for the synthesis of peptide nucleic acid (PNA) is described. First, a resin-bound amino acid is alkylated under Fukuyama-Mitsunobu conditions. A nucleobase is then incorporated via an acid fluoride. Subsequently, oligomerization may be achieved by deprotection, coupling of another amino acid, and repetition of the cycle. Each step of the submonomer synthesis has been optimized to provide essentially quantitative yield.
