The cyclization of N6-(ω-hydroxyalkyl)adenines with a N6H-group leads to N6,N1 ring closure regardless of the method of the cyclization that was used. Five-membered to eight-membered rings were obtained using NBS/PPh3; however, under Mitsunobu conditions, the eight-membered fused purine was not formed. Surprisingly, the cyclization of N6-methyl-N6-(4-hydroxybutyl)adenine only leads to N6,N7 ring closure using both methods.

(R)-3-(2′-hydroxyprop-1-yl) adenine 4 was obtained by alkylation of adenine 1 with R-propylene carbonate 2 in the presence of pulverized sodium hydroxide in the synthetic process of tenofovir. The elucidation of the structure of 4 was confirmed by single crystal X-ray diffraction and NMR experiments such as 1D 1H, 13C, and DEPT, as well as 2D COSY, HSQC, and HMBC spectra.
