Nucleophilic Reaction upon Electron-Deficient Pyridone Derivatives. XIII. Regioselective Synthesis of 2-Substituted 3-Nitropyridines by One-Pot Reaction of Either 4- or 6-Substituted 1-Methyl-3,5-dinitro-2-pyridones with Ketones and Ammonia
A one-pot synthesis of 2-substituted 3-nitropyridines was developed by a ring transformation of 6- or 4-substituted 1-methyl-3,5-dinitro-2-pyridones (2 or 3) with ammonia and enamines derived from ketones. Some intermediates having a 2,6-diazabicyclo[3.3.1]nonane skeleton were isolated from reactions of 3. The ring transformation proceeds via an addition-addition-elimination-elimination mechanism.
The present invention comprises benzodiazepine compounds having farnesyl transferase inhibitory activity.

(EN) This invention relates to compounds that inhibit farnesyl-protein transferase and ras protein farnesylation, thereby making them useful as anti-cancer agents. The compounds are also useful in the treatment of diseases, other than cancer, associated with signal transduction pathways operating through ras and those associated with proteins other than ras that are also post-translationally modified by the enzyme farnesyl protein transferase. The compounds may also act as inhibitors of other prenyl transferases, and thus be effective in the treatment of diseases associated with other prenyl modifications of proteins.(FR) La présente invention concerne des composés inhibant la farnésyl-transférase et la farnésylation de la protéine Ras, ce qui en fait d'utiles agents anticancéreux. Ces composés conviennent également particulièrement au traitement de maladies autres que le cancer, associées aux canaux de transduction de signaux par la protéine Ras, et de maladies associées à des protéines autres que les protéines Ras qui subissent une modification post-translationnelle sous l'effet de la farnésyl-transférase. Ces composés se comportent également comme inhibiteurs d'autres prényl-transférases, et peuvent de ce fait convenir au traitement d'affections associées à d'autres modifications prényl des protéines.

Regioselective synthesis of 2-substituted 3-nitropyridines was achieved by one-pot reaction of either 4- or 6-substituted 1-methyl-3,5-dinitro-2-pyridones with ketones in the presence of ammonia. The selectivity is interpreted in terms of steric factor of substituent on the pyridone.
