Glycosylhydrazine, 5. Aufbauende Synthese der 5‐Säureamid‐Derivate von Pyrazol‐, Pyrazolo[3,4‐d]pyrimidin‐ und 1H ‐1,2,4‐Triazol‐nucleosiden

Abstract: Aus den Riburonamid-hydrazonen 4a -c wurden in einer Eintopfreaktion regio-und stereoselektiv die 5'-Saureamid-Derivate des 3,5-Dimethylpyrazol-nucleosids 6a,c, der funktionell substituierten Pyrazol-nucleoside 9a und 10b und des 1 H-l,2,4-Triazol-nucleosids 18 direkt aufgebaut. Als Allopurinolribosid-Derivate wurden aus 9a und 10b die ungeschutzten Pyrazolo [3,4-d]pyrimidin-nucleosid-5'-saureamide 14a und 15 b hergestellt. Entsprechend wurde aus 18 das Ethylamid 20 der VirazoL5'-saure erhalten.

“…The spectral data for this compound (UV, IR 1H NMR) were identical in all respects with those previously reported.8"19 4 6-Bis (dimethylamino)-1-0-DE-ribofuranosvlp razolo 13. 4-i]primidine (10). To a solution of 7 (1.75 g, 3.9 mel) in NlOH (50 mL) was added 40% aqueous dimethyl amine (50 mL) and the mixture was stirred at room temperature for 16 hours.…”
