Abstract

The preparation of mixed-sequence PNAs (PNAs containing the four natural nucleobases; thymine, cytosine, adenine, and guanine) is described. The PNA monomers containing thymine, Cbz-protected cytosine, or adenine or benzyl-protected guanine were prepared via convergent syntheses. Subsequent to introduction of the carboxymethyl linker at N-1 of the pyrimidines or N-9 of the purines and suitable protection of exocyclic groups, the ...
