Darstellung und Eigenschaften einiger 6‐ und 2.6‐substituierter Purine

Abstract: Ausgehend von 6-Methyl-purin (10) wurden durch Anwendung der Orfolew-King-und Krolznke-Reaktionen das Am1 N N-Dimethyl-N -[purinyI-(6)-methylen]-p-phenylendiamin (2) und mehrere Punn-aldehyd-(6)-Derivate (5 -9) hergestellt Es wird uber die Oxydation und Nitrosierung des 6-Methyl-purins berichtet sowie die Darstellung ueiterer Derivate von 2-Ammo-purin-aldehyd-(6) beschrieben Analoge Verbindungen zu den heterocyclischen Basen der Nucleinsauren wurden wahrend der vergangenen Jahre dargestellt in der Hoffnung, da… Show more

“…On the other hand, 6-lithiated purine is much more reactive but is stable only for a few minutes at −130 °C . Indirect routes from 6-methylpurine: oxidation to aldehyde followed by reduction or rearrangement of its N -oxide with Ac 2 O to 6-(acetoxymethyl)purine gave low yields.…”

“…Recently, the use of cytotoxic 6-methylpurine base liberated by purine nucleoside phosphorylases from its nontoxic deoxyribonucleoside was proposed as a novel principle in the gene therapy of cancer . 6-Methylpurines are also versatile starting materials for further modifications of the methyl group leading to 6-formyl- or 6-halomethylpurines, purine-6-carboxamides, etc.…”

“…The cyano group in the 6-position is usually incorporated through cyanide ion substitution of either 6-iodo, 8 6-chloro, 9 6-tosyl, 10 6-methylsulfonyl, 11 or 6-trimethylammonium 12 purine derivatives, and also by dehydration of the 6-oximo derivative. 13 Phenolic 6-cyanopurines 4 have great potential as new antifungal scaffolds because they are structurally related to 6-substituted aminopurines 1 and also to benzimidazole antifungal agents, which are widely used in crop protection. 14 The present work describes a convenient and efficient synthesis of 2-hydroxyphenyl-4,5-dicyano-N-(N'-alkoxyformimidoyl)imidazoles and 6-cyano-8-hydroxyphenylpurines.…”
