(1R*,4R*,7S*)-7-Aminobicyclo[2.2.1]hept-5-ene-2,2-dimethanol (15) was prepared in four easy steps from bicyclo[2.2.1]hept-5-ene-2,2-dimethanol (10). Reaction of amine 15 with ethyl N-((E)-3-ethoxymethacryloyl)carbamate afforded thymine derivatives 17a. The amine 15 was used to construct 6-chloro-9H-purine derivative 19a, 2-amino-6-chloro-9H-purine derivative 22a. Ammonolysis of 19a led to the adenine derivative 20a. Treatment of 22a with trifluoroacetic acid afforded guanine nucleoside 23a. (1R*,4R*,7S*)-7-[6-(Cyclopropylamino)-9H-purin-9-yl]bicyclo[2.2.1]hept-5-ene-2,2-dimethanol (21a) and (1R*,4R*,7S*)-7-[2-amino-6-(cyclopropylamino)-9H-purin-9-yl]bicyclo[2.2.1]hept-5-ene-2,2-dimethanol (24a) were prepared by aminolysis of 19a and 22a. Saturated nucleosides 17b, 20b, 21b, 23b, 24b were obtained by hydrogenation on palladium catalyst.

The Way

The current synthesis of racemic purine and pyrimidine isoxazoline-carbocyclic nucleosides is reported, detailing the key-steps for standard and reliable preparations. Improved yields were obtained by the proper tuning of the single synthetic steps, opening the way for the preparation of a variety of novel compounds. Some of the obtained compounds were also evaluated against a wide variety of DNA and RNA viruses including HIV. No specific antiviral activity was observed in the cases at hand. Novel compounds were prepared for future biological tests.
