Abstract

(S,S)- and (R,R)-β,γ-Bis-substituted PNAs were synthesized from the C-2 symmetric vicinal diamine system embedded in 1,4 dihydroxybutane and 1,4-dimethoxybutane scaffolds. (R,R)-β,γ-Bis-methoxymethyl-PNA derived from D-tartaric acid was found to be in the right configuration and conformation to be an excellent mimic of PNA, endowed with superior ability to enter into cells.
