  A novel bibracchial lariat ether based upon 1,4,10,13-tetraoxa-7,16-diazacyclooctadecane (A2O3T3A) has been prepared which has CH2CH2adenine (2A) and CH2CH2CH2thymineOCH2CH2adenine (3T3A) side-arms; the terminal adenine in the 3T3A side-arm folds parallel to and π-stacks with the thymine in the same side-arm while the adenines in opposite side-arms form a single hydrogen bond as judged by two-dimensional NOESY studies.

  Two new bibracchial lariat ethers have been prepared as flexible model systems for nucleotide H-bonding and pi-stacking interactions. In both compounds, nucleotide bases terminate side arms attached at the nitrogen atoms of a diaza-18-crown-6 macroring. Each side arm is terminated by one or more nucleotide bases. The unsymmetrical structure is ade-CH2CH2CH2CH2CH2-thy-CH2CH2-ade (A-O-T-A). The symmetrical compound is ade-CH2CH2-thy-CH2CH2CH2CH2CH2CH2-thy-CH2CH2-ade (A-T-O-T-A). NMR studies show that the thy-ade side arm organizes by pi-stacking in both A-O-T-A and A-T-O-T-A. Both compounds exhibit hydrogen bonding between the stacked base pair and the opposite adenine. A-O-T-A exhibits a stronger interaction resulting from the enforced interplay of noncovalent forces, as evidenced by one- and two-dimensional NMR experiments. This compound also presented the opportunity to detect and examine single hydrogen-bonded interactions between two adenine bases. The effects of conformational rigidity, side arm orientation, metal ion complexation, and variations in solvent were assessed for both compounds. The results presented here indicate that an increase in the medium's dielectric constant or complexation of metal cations appear to modulate the interplay between hydrogen bonding and stacking interactions.
