- W2012083372 abstract "1,5-Dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-ones 5 and 6 were prepared by reaction of the corresponding ethyl 5-aminopyrazole-4-carboxylate with triethyl orthoformate and amines. Ethyl N-(4-methoxyphenyl)formimidate and N,N′-bis(4-methoxyphenyl)formamidine could also be used as the ring closing reagent. The Mannich bases 13 and 14 were produced in a reaction of 9 with formaldehyde and piperidine. The ribosides 15 were obtained by melting a mixture of 9 and 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose in the presence of p-toluenesulphonic acid. Synthese von 1,5-Dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-onen und ihrer Riboside und Mannichbasen Bei der Umsetzung von 5-Aminopyrazol-4-carbonsäure-ethylester (2) mit Orthoameisensäure-triethylester und Aminen wurden die 1,5-Dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one 5 und 6 erhalten. Auch N-(4-Methoxyphenyl)-formimidsäure-ethylester und N,N′-Bis(4-methoxyphenyl)-formamidin konnten als Ringschlußreagenzien verwendet werden. 9 wurde mit Formaldehyd und Piperidin in die Mannich Basen 13 und 14 überführt. Schmelzen von 9 und 1,2,3,5-Tetra-O-acetyl-β-D-ribofuranose mit einer katalytischen Menge Toluol-4-sulfonsäure lieferte die Riboside 15." @default.
