A quadruply hydrogen bonded heterocomplex displaying high-fidelity recognition

An exceptionally strong quadruply hydrogen-bonded complex is formed between 2,7-diamido-1,8-naphthyridine 3 (DAN) and the butylurea of guanosine 6 (UG) in chloroform. The UG unit can be prepared in four steps from guanosine on a 10 g scale in excellent yields without chromatographic purification. The association constant (Kassoc ≈ 5 × 107 M-1) for the UG·DAN complex determined by fluorescence energy transfer from the naphthyridine unit of 3 to coumarin 343 covalently linked UG (18) is among the highest reported for a neutral DNA base-pair analogue. The weak self-association of DAN (Kdimer -1) and UG (Kdimer ca. 200-300 M-1) means that the UG·DAN complex forms with unparalleled fidelity.
