Regioselective Nitration of Halogenated Benzo[c]cinnolines and Benzenoids.

ABSTRACT: Electrophilic nitration of halo-substituted benzo[c]cinnolines and benzenoids has been achieved regioselectively. The nitro group entry was always ortho to the halo group or/and the aromatic ring. This regioselective electrophilic ortho-nitration was accomplished in mixed acid/mild temperature conditions. Regioselectivity ortho to the halo/ring group(s) was observed with or without proximal steric hindrance. Chlorides and bromides worked equally well in directing these high-yielding ortho-selective reactions.

Phosphomolybdic acid hydrate encapsulated in MIL-53 (Fe): a novel heterogeneous heteropoly acid catalyst for ultrasound-assisted regioselective nitration of phenols.

Project description:In this study, a heterogeneous catalyst, PMA@MIL-53 (Fe) (MIL ⇒ Matériaux de l'Institut Lavoisier), has been used to replace the usual mineral acids such as sulfuric acid. A wide variety of nitration methods require the use of a mixture of acids such as concentrated nitric acid and sulfuric acid, which result in producing a large amount of acidic waste. During recent years, the use of the heterogeneous system for the nitration of aromatic compounds has been highly considered and used by chemists due to some specific advantages, i.e. easy separation of the product from the reaction mixture, the possibility of recycling and reusing the catalyst, etc. Herein, the catalyst was synthesized using a metal-organic framework and a heteropoly phosphomolybdic acid. The PMA@MIL-53 (Fe) was prepared using a similar method of MIL-53 (Fe) synthesis. Afterwards, FeCl3·6H2O and 1,4-benzene dicarboxylic acid (BDC) in a dimethylformamide solution were placed in an ultrasound bath and, then, HPA (heteropoly acid) was added to the reaction mixture. The PMA (phosphomolybdic acid) encapsulation in MIL-53 (Fe) was confirmed using various analysis. Under optimal conditions, the catalytic activity of PMA@MIL-53 (Fe) was evaluated in nitration of phenol under ultrasonic waves. Besides, the ratio of the two products of ortho and para was obtained using GC. Optimum conditions were reached after 15 minutes, in such a way that the loaded PMA was 0.02 g under optimal conditions, the efficiencies of ortho-nitrophenol and para nitrophenol were 54.98 and 45.01, respectively.

Green Synthesis of Halogenated Thiophenes, Selenophenes and Benzo[b]selenophenes Using Sodium Halides as a Source of Electrophilic Halogens.

Project description:Herein, we report the first synthesis of chlorinated benzo[b]selenophenes via environmentally friendly electrophilic chlorocyclization reaction using "table salt" as a source of "electrophilic chlorine" and ethanol as a solvent. In addition, the synthesis of diverse halogenated heterocycles, including 3-chloro, 3-bromo and 3-iodo thiophenes, selenophenes, and benzo[b]selenophenes was successfully accomplished under the same environmentally benign reaction conditions. This methodology has several advantages over other previously reported reactions as it employs simple starting compounds, an environmentally friendly solvent, ethanol, and non-toxic inorganic reagents under mild reaction conditions, resulting in the high product yields.

Discovery of 1<i>H</i>-benzo[<i>d</i>]imidazole-(halogenated) Benzylidenebenzohydrazide Hybrids as Potential Multi-Kinase Inhibitors.

Project description:In an effort to develop improved and effective targeted tyrosine kinase inhibitors (TKIs), a series of twelve novel compounds with the structural motif "(E)-4-(((1H-benzo[d]imidazol-2-yl)methyl)amino)-N'-(halogenated)benzylidenebenzohydrazide" were successfully synthesized in three steps, yielding high product yields (53-97%). Among this new class of compounds, 6c and 6h-j exhibited excellent cytotoxic effects against four different cancer cell lines, with half-maximal inhibitory concentration (IC50) values ranging from 7.82 to 21.48 μM. Notably, compounds 6h and 6i emerged as the most potent inhibitors, demonstrating significant activity against key kinases such as EGFR, HER2, and CDK2. Furthermore, compound 6h displayed potent inhibitory activity against AURKC, while 6i showed potent inhibitory effects against the mTOR enzyme, with excellent IC50 values comparable with well-established TKIs. The mechanistic study of lead compound 6i revealed its ability to induce cell cycle arrest and apoptosis in HepG2 liver cancer cells. This was accompanied by upregulation of pro-apoptotic caspase-3 and Bax and downregulation of anti-apoptotic Bcl-2. Additionally, molecular docking studies indicated that the binding interactions of compounds 6h and 6i with the target enzymes give multiple interactions. These results underscore the ability of compound 6i as a compelling lead candidate warranting further optimization and development as a potent multi-targeted kinase inhibitor, which could have significant implications for the treatment of various cancers. The detailed structural optimization, mechanism of action, and in vivo evaluation of this class of compounds warrant further investigation to assess their therapeutic potential.

Electrochemical Nitration with Nitrite.

Project description:Aromatic nitration has tremendous importance in organic chemistry as nitroaromatic compounds serve as versatile building blocks. This study represents the electrochemical aromatic nitration with NBu4 NO2 , which serves a dual role as supporting electrolyte and as a safe, readily available, and easy-to-handle nitro source. Stoichiometric amounts of 1,1,1-3,3,3-hexafluoroisopropan-2-ol (HFIP) in MeCN significantly increase the yield by solvent control. The reaction mechanism is based on electrochemical oxidation of nitrite to NO2 , which initiates the nitration reaction in a divided electrolysis cell with inexpensive graphite electrodes. Overall, the reaction is demonstrated for 20 examples with yields of up to 88 %. Scalability is demonstrated by a 13-fold scale-up.

Structure/reactivity relationships in the benzo[c]phenanthrene skeleton: stable ion and electrophilic substitution (nitration, bromination) study of substituted analogues, novel carbocations and substituted derivatives.

Project description:A series of novel carbocations were generated by low-temperature protonation of substituted benzo[c]phenanthrenes, B[c]Phs, and their charge delocalization pathways were elucidated by NMR on the basis of the magnitude of Deltadelta13C values. It has been shown that the protonation regioselectivity is strongly controlled by methoxy and hydroxyl substituents, whose directive effects override methyl substitution effects. Regiocontrol by -OMe and -OH substituents, and its stronger influence relative to methyl groups, was also observed in the nitration and bromination reactions. Charge distribution modes in the regioisomeric protonated carbocations formed via parent B[c]Ph as well as in the benzylic carbocation formed via fjord-region epoxide ring opening were deduced by gauge-invariant atomic orbital density functional theory (GIAO-DFT) and from the natural population analysis (NPA)-derived changes in charges over CHs. These patterns were compared with those derived from NMR experiments in the substituted derivatives. NMR-based charge delocalization mapping provided insight into structure/activity relationships in the methylated and fluorinated B[c]Phs. Regioselectivities observed in the nitration and bromination reactions in representative cases are the same as those via protonations. Among a group of novel nitro and bromo derivatives synthesized in this study are examples, where the nitro group is introduced into the fjord region, for which the X-ray structure could be obtained in one case.

Chemical structure and biodegradability of halogenated aromatic compounds. Halogenated muconic acids as intermediates.

Project description:Substituted muconic acids were prepared from the corresponding catechols by pyrocatechase II from Pseudomonas sp. B13. The stabilities of substituted muconic acids were compared under different pH conditions. 3-Substituted cis, cis-muconic acids cycloisomerized readily in slightly acidic solutions, whereas 2-chloro- and 2-fluoro-cis,cis-muconic acids were stable under these conditions and could be isolated as crystalline compounds. They were isomerized to the cis, trans-form in highly acidic solution (pH 1), particularly when heated to 80 degrees C. Cycloisomerization of 2-chloro-cis,cis-muconic acid in 75% (v/v) H2SO4 yields 4-carboxymethyl-2-chloro-but-2-en-4-olide (4-chloro-2,5-dihydro-5-oxo-3H-furan-2-ylacetic acid). THe cis,cis-configuration of 2-chloromuconic acid was certified by 1H n.m.r. spectroscopy and by enzymic cycloisomerization. Although the cis,cis-configuration of 2-fluoromuconic acid was confirmed by corresponding spectroscopic data, it was not cycloisomerized by crude extracts or cycloisomerase II preparations from Pseudomonas sp. B13.
