Synthesis of New Derivatives of 4-Methyl-3-nitro-6H-pyrimido[2,1-b]quinazoline
摘要:
-Various derivatives of 2-chloro-4-methyl-5-nitropyrimidine were synthesized by the reaction of 2,4-dichloro-6-methyl-5-nitro pyrimidine with amines. The synthesized derivatives were reacted with 2-aminobenzyl alcohol in m-xylene to obtain derivatives of a novel 4-methyl-3-nitro-6H-pyrimido[2,1-b]quinazoline heterocyclic system. The composition and structure of the products was confirmed by CHN analysis, IR, H-1 NMR, and C-13 NMR spectroscopy, and mass spectrometry.

Es werden neue 9-(ω-Heteroarylamino-alkylamino)-erythromycine der Formel
deren pharmakologisch verträgliche Säureadditionssalze mit anorganischen oder organischen Säuren, Verfahren zur Herstellung dieser Verbindungen, die Verwendung der Verbindungen und diese Verbindungen enthaltende Arzneimittel beschrieben. In der obigen allgemeinen Formel (I) bedeutet E die Erythromycylgruppe, n die Zahlen 2 oder 3 und R bestimmte aromatische Heterocyclen, wie eine ebenfalls substituierte 2-Pyrimidinylgruppe, 2-Chinazolinylgruppe oder heterocyclisch kondensierte Pyrimidinylgruppe. Die Verbindungen der Formel und ihre Salze sind stark wirksam gegen grampositive und gramnegative Bakterien; die diese Verbindungen enthaltenden Arzneimittel sind Breitband-Antibiotika.
