A novel efficient synthetic method for a functionalized PNA (peptide nucleic acid) is described, in which a functional molecule is incorporated in place of a nucleobase. Novel ω-AA-BocPNA-OH (20-24, AA=amino acid) were designed as PNA precursor monomer units into which functional molecules could be incorporated efficiently. Compounds 20-24 reacted quantitatively with OSu (N-hydroxysuccinimidyl) active ester derivatives and isothiocyanate derivatives of commercial functional molecules to give target functionalized PNA monomer units 25-53. Various types of functionalized PNA monomer units could be efficiently incorporated into multiple predetermined positions in a PNA oligomer by SPPS (solid phase peptide synthesis) in the same way as for the four A(Cbz), G(Cbz), C(Cbz), and T PNA monomer units.
