A convergent and cost-effective strategy to synthesize enantiospecific nucleoside/ nucleotide analogs from readily available อฐ-amino acids has been described. Both (L)-and (D)-methionine were transformed in four steps to the corresponding key intermediates (L)-and (D)-2-(tertbutyloxycarbonylamino)-4

โฆ Synopsis
The first solid-phase synthesis of novel peptide-derived enantiospecific nucleic acid analogs (PDNAs), employing all three stereoisomers of 4-(N 9 -adeninyl)-2-amino(t-boc)-butyric acid as ADNA (amino acid-derived nucleoside analogs) monomers has been described. The preliminary melting temperature (T m ) data obtained by hybridization experiments demonstrated that these PDNAs can anneal to their complementary nucleic acid strand dT 10 .
