Unusual radical addition on a heteroaromatic nitrogen. A convenient access to new pyrimidine derivatives.
A radical generated on the side-chain of a 2- or 4-N-alkylamino-4,6- or 2,6-dichloropyrimidine can cyclise on the nitrogen or on the carbon of the pyrimidine ring depending on its position and on whether an acetyl or a Boc group is present on the extra-nuclear nitrogen.
متن کاملSynthesis and antibacterial properties of pyrimidine derivatives.
In this study, a series of syntheses was conducted on the pyrimidine system, obtaining bisulfite carboxyl derivatives 4 and hydroxy derivatives 5. In addition, a series of syntheses were carried out as a result of which both alkyl and aromatic amines were obtained. Then, the attempt was made to cyclize these amines in the Mannich reaction to pyrimido[4,5-d]pyrimidines 11, 12. After determinatio...

متن کاملSynthesis and Antimicrobial Activity of some Tetrahydro Quinolone Diones and Pyrano[2,3-d]pyrimidine Derivatives
There has been special interest in the chemistry of quinolone and pyrimidine derivatives due to their diverse biological activities such as anticonvulsant, anti-malarial agents, antibacterial, antiviral, cytostatic, antithelemintic, antigenotoxic, anti-cancer agents. These compounds are also used as targeting delayed-type hypersensivity and anti-convulsant agents. As a part of our research work...
