Abstract

A complete analysis of the ^1^H and ^13^C spectra of the representative series of heteroaryl vinyl ethers and sulfides and heteroaryl styryl sulfides was carried out. The electronic and spatial structures of these compounds are discussed. It was shown that the C—H· · ·N intramolecular interactions in the investigated molecules influence significantly the spectral parameters and the conformational equilibrium.

It has previously been shown that formaldehyde causes the formation of hydroxymethylated derivatives with nucleobases, but these were identified after separation of the reaction products; such handling might destroy labile derivatives or remove products present in small proportions.

The 'H and I3C NMR spectra of a series of structurally related crown ethers have been recorded, and the signals assigned by means of 'H/I3C heteronuclear correlated and 'H/'H homonuclear NOE difference spectroscopy. The NMR parameters so extracted have been used to discuss the preferred, rapidly int

Using 'H, 13C and =N NMR it has been concluded that 3-deazapurine protonates exclusively at N-1 with a pK of about 5.6. The base exhibits rapid tautomerism with proportions of 70:30, with the N-7-H tautomer in the majority. The salt exists predominantly as the N-7-H tautomer. 1-Deazapurine protonate
