Guanosine has been reacted with triformylmethane (TFM) in refluxing pyridine. Four different products, 4-7, were isolated by preparative RP-HPLC, and characterized by H-1 and C-13 NMR and UV spectroscopy and mass spectrometry. One of the products, the cyclic 1:1 adduct 4, is a stable cyclic carbinolamine formed probably by cyclization of the expected aminomethylene derivative 3. Compound 4 then undergoes reversible dehydration to the fully conjugated adduct 5. The appearance of the additional adducts, 6 and 7, suggests that TFM is prone to transformations resulting in the formation of methylenemalonaldehyde (9) and 1,1,3,3-tetraformylpropane (11).

myl[2, 1-i]pyrimidopurine (pfA-dR), 3-(2-deoxy-beta-D-ribofuranosyl)-7H-8-carboxy[2,1-i]pyrimidopurine++ + (pcA-dR), and 4-(N(6)-2-deoxyadenosinyl)-3-formyl-2-hydroxy-3-butenoic acid (OH-fbaA-dR). In the reactions performed at pH 7.4 and 37 degrees C, the yields of pfA-dR, pcA-dR, and OH-fbaA-dR were 1.1, 6.7, and 5.5 mol %, respectively. The adduct pfA-dR was detected also in calfthymusDNA reacted
