Abstract
A one-pot cascade chlorination/heterocyclization strategy has been developed for the synthesis of 2,4-dichloro-substituted quinolines from acylated anilines using triphosgene and triphenylphosphine oxide. Obviating the conventional harsh conditions of chlorination, synthetic useful quinolines with moderate to good yields were obtained through this reaction. The mechanism study exhibited that the formation of a β-enamine intermediate plays a vital role in the generation of the final product.

Abstract
The drug-resistance problem is widely spread and becoming more common in community-acquired and nosocomial strains of bacteria. Therefore, finding new antimicrobial agents remains an important drug target. From this perspective, new derivatives of benzothiazole were synthesized and evaluated for their antimicrobial activity and ability to inhibit the DHPS enzyme. The synthesis was carried out by the reaction of benzothiazole N-arylsulphonylhydrazone with N-aryl-2-cyano-3-(dimethylamino)acrylamide, N-aryl-3-(dimethylamino)prop-2-en-1-one, arylaldehydes or diazonium salt of arylamine derivatives, which led to the formation of N-arylsulfonylpyridones 6a-d (yield 60-70%) and 12a-c (yield 50-60%),N-(2-(benzo[d]thiazole-2-yl)-3-arylacryloyl-4-methylsulfonohydrazide 14a-c (yield 60-65%), 4-(benzo[d]thiazole-2-yl)-5-aryl-1H-pyrazol-3(2H)-one 16a-c (yield 65-75%), and N'-(2-(benzo[d]thiazol-2-yl)-2-(2-arylhydrazono)acetyl)-4-arylsulfonohydrazide 19a-e (yield 85-70%). The antimicrobial evaluations resulted into a variety of microbial activities against the tested strains. Most compounds showed antimicrobial activity against S. aureus with an MIC range of 0.025 to 2.609 mM. The most active compound, 16c, exhibited superior activity against the S. aureus strain with an of MIC 0.025 mM among all tested compounds, outperforming both standard drugs ampicillin and sulfadiazine. The physicochemical-pharmacokinetic properties of the synthesized compounds were studied, and it was discovered that some compounds do not violate rule of five and have good bioavailability and drug-likeness scores. The five antimicrobial potent compounds with good physicochemical-pharmacokinetic properties were then examined for their inhibition of DHPS enzyme. According to the finding, three compounds, 16a-c, had IC50 values comparable to the standard drug and revealed that compound 16b was the most active compound with an IC50 value of 7.85 μg/mL, which is comparable to that of sulfadiazine (standard drug) with an IC50 value of 7.13 μg/mL. A docking study was performed to better understand the interaction of potent compounds with the binding sites of the DHPS enzyme, which revealed that compounds 16a-c are linked by two arene-H interactions with Lys220 within the PABA pocket.

Abstract
AbstractTrifluoromethanesulfonic anhydride (Tf2O) is utilized as a strong electrophilic activator in a wide range of applications in synthetic organic chemistry, leading to the transient generation of a triflate intermediate. This versatile triflate intermediate undergoes nucleophilic trapping with diverse nucleophiles to yield novel compounds. In this review, we describe the features and applications of triflic anhydride in organic synthesis reported in the past decade, especially in amide, sulfoxide, and phosphorus oxide chemistry through electrophilic activation.

Abstract
EGFR has a key role in cell growth. Its mutation and overexpression share in epithelial malignancies and tumor growth. Quinazoline and quinoline derivatives are common anticancer intracellular inhibitors of EGFR kinase, and their optimization is an important issue for development of potent targeted anticancer agents. Based on these facts, different strategies were used for optimizing our reported quinoline-3-carboxamide compound III (EGFR IC50 = 5.283 µM and MCF-7 IC50 = 3.46 µM) through different molecular modeling techniques. The optimized compounds were synthesized and subjected to EGFR binding assay and accordingly some more potent inhibitors were obtained. The most potent quinoline-3-carboxamides were the furan derivative 5o; thiophene derivative 6b; and benzyloxy derivative 10 showing EGFR IC50 values 2.61, 0.49 and 1.73 μM, respectively. Furthermore, the anticancer activity of compounds eliciting potent EGFR inhibition (5o, 5p, 6b, 8a, 8b, and 10) was evaluated against MCF-7 cell line where they exhibited IC50 values 3.355, 3.647, 5.069, 3.617, 0.839 and 10.85 μM, respectively. Compound 6b was selected as lead structure for further optimization hoping to produce more potent EGFR inhibitors.

Abstract
The cannabinoid type 2 receptors (CB2Rs) play crucial roles in inflammatory diseases. There has been considerable interest in developing potent and selective ligands for CB2R. In this study, quinoline-2,4(1H,3H)-dione analogs have been designed, synthesized, and evaluated for their potencies and binding properties toward the cannabinoid type 1 receptor (CB1R) and CB2R. C5- or C8-substituted quinoline-2,4(1H,3H)-diones demonstrate CB2R agonist activity, while the C6- or C7-substituted analogs are antagonists of CB2R. In addition, oral administration of 21 dose-dependently alleviates the clinical symptoms of experimental autoimmune encephalomyelitis in a mouse model of multiple sclerosis and protects the central nervous system from immune damage. Furthermore, the interaction modes predicted by docking simulations and the 3D-QSAR model generated with CoMFA may offer guidance for further design and modification of CB2R modulators.

Abstract
EGFR, which plays a vital role as a regulator of cell growth, is one of the intensely studied TK targets of anticancer inhibitors. The most two common anticancer inhibitors are anilinoquiazolines and anilinoquinolines that inhibit EGFR kinase intracellularly. The present investigation dealt with design (pharmacophore, docking and binding energy) and synthesis of a new series of 4-anilinoquinoline-3-carboxamide derivatives as potential anticancer agents targeting EGFR. All the newly synthesized compounds were screened for their anticancer activity against MCF-7 and compounds 4f, 7a and 7b showed significant activity with IC50 values 13.96 μM, 2.16 μM and 3.46 μM, respectively. Most of the synthesized compounds were subjected to enzyme assay (EGFR TK) for measuring their inhibitory activity with the determination of IC50 values and the preliminary results revealed that compound 7b, which had potent inhibitory activity in tumor growth and had potent activity on the EGFR TK enzyme with 67% inhibition compared to ATP would be a potential anticancer agent.

Abstract
Fluoro-substituted aliphatic nitriles are shown to undergo the Houben-Hoesch reactions with arenes in CF(3)SO(3)H to give fluoro-substituted ketones in good yields. The fluorine substituents appear to enhance the reactivities of the nitriles (and the nitrilium ion intermediates) compared to similar aliphatic nitriles. Fluoro-substituted ketones are also shown to be accessible through the reactions of organometallic reagents and fluoro-substituted nitriles.

Abstract
Viridicatin derivatives were synthesized from cyanoacetanilides utilizing the CN groups as electron-withdrawing groups and leaving groups. Also, the key scaffolds of glycocitlones were constructed via the intramolecular Houben-Hoesch-type reactions of cyanoacetanilides where the CN groups functioned as electrophiles. It was found that Houben-Hoesch-type reactions of cyanoacetanilides were promoted by α-functionalization such as perfluoroacylation and N,N-dimethylaminomethylenation and that introduction of such substituents at α-position with respect to the CN groups greatly influenced the physical properties and chemical reactivity of the CN groups.
