On April 30, 1991, Seela, F.; Rosemeyer, H.; Gumbiowski, R.; Mersmann, K.; Muth, H. P.; Roeling, A. published an article.Formula: C6H4ClN3O The title of the article was Base-modified purine 2′,3′-dideoxyribonucleosides: synthesis via deoxygenation or direct nucleobase anion glycosylation. And the article contained the following:
A symposium report. 5-Aza-7-deazapurine, 5-aza-1,7-dideazapurine, and 8-azapurine 2′,3′-dideoxy-D-ribonucleosides were synthesized and inhibitory activity against HIV reverse transcriptase and DNA-polymerases was evaluated. The experimental process involved the reaction of 7-Chloroimidazo[1,2-a]pyrimidin-5(1H)-one(cas: 57473-33-3).Formula: C6H4ClN3O
The Article related to purine dideoxyribonucleoside base modified symposium, deoxygenation nucleoside symposium, nucleobase anion glycosylation symposium, hiv reverse transcriptase inhibitor symposium, dna polymerase inhibitor symposium, aids inhibitor purine dideoxyribonucleoside symposium, azadeazapurine dideoxyribonucleoside symposium and other aspects.Formula: C6H4ClN3O
