title: Pyrrolidine nucleic acids: DNA/PNA oligomers with 2-hydroxy/aminomethyl- 4-(thymin-1-yl)pyrrolidine-N-acetic acid.
abstract: Synthesis of pyrrolidine-based chiral positively charged DNA analogues is reported. The synthesis of (2S,4S) and (2R,4R) thymin-1-ylpyrrolidine-N-acetic acid, its site specific incorporation in PNA:DNA chimera and PNA, and the study of their binding properties with complementary DNA/RNA sequences is presented.
