Study of Biological Activities and ADMET-Related Properties of Novel Chlorinated N-arylcinnamamides

A series of eighteen 4-chlorocinnamanilides and eighteen 3,4-dichlorocinnamanilides were designed, prepared and characterized. All compounds were evaluated for their activity against gram-positive bacteria and against two mycobacterial strains. Viability on both cancer and primary mammalian cell lines was also assessed. The lipophilicity of the compounds was experimentally determined and correlated together with other physicochemical properties of the prepared derivatives with biological activity. 3,4-Dichlorocinnamanilides showed a broader spectrum of action and higher antibacterial efficacy than 4-chlorocinnamanilides; however, all compounds were more effective or comparable to clinically used drugs (ampicillin, isoniazid, rifampicin). Of the thirty-six compounds, six derivatives showed submicromolar activity against Staphylococcus aureus and clinical isolates of methicillin-resistant S. aureus (MRSA). (2E)-N-[3,5-bis(trifluoromethyl)phe-nyl]-3-(4-chlorophenyl)prop-2-enamide was the most potent in series 1. (2E)-N-[3,5-bis(Trifluoro-methyl)phenyl]-3-(3,4-dichlorophenyl)prop-2-enamide, (2E)-3-(3,4-dichlorophenyl)-N-[3-(trifluo-romethyl)phenyl]prop-2-enamide, (2E)-3-(3,4-dichloro-phenyl)-N-[4-(trifluoromethyl)phe-nyl]prop-2-enamide and (2E)-3-(3,4-dichlorophenyl)-N-[4-(trifluoromethoxy)phenyl]prop-2-en-amide were the most active in series 2 and in addition to activity against S. aureus and MRSA were highly active against Enterococcus faecalis and vancomycin-resistant E. faecalis isolates and against fast-growing Mycobacterium smegmatis and against slow-growing M. marinum, M. tuberculosis non-hazardous test models. In addition, the last three compounds of the above-mentioned showed insignificant cytotoxicity to primary porcine monocyte-derived macrophages.

Copper-catalyzed direct transformation of secondary allylic and benzylic alcohols into azides and amides: An efficient utility of azide as a nitrogen source

A mild and convenient method for the synthesis of amides has been explored by using secondary alcohols, Cu(ClO4)2·6H2O as a catalyst, and trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) at ambient temperature. This method has been successfully adapted to the preparation of azides directly from their corresponding alcohols and offers excellent chemoselectivity in the formation of ω-halo azides and the azidation of allylic alcohols in the presence of a benzyl alcohol moiety. In addition, this strategy provides an opportunity to synthesize azides that can serve as precursors to β-amino acids. A mild and convenient method for the synthesis of amides has been explored by using secondary alcohols, Cu(ClO4)2·6H2O as a catalyst, and trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) at ambient temperature. This method has also been adapted to the preparation of azides directly from their corresponding alcohols.

DDQ-promoted direct transformation of benzyl hydrocarbons to amides via tandem reaction of the CDC reaction and Beckmann rearrangement

An atom-efficient and transition metal-free approach to amides from the corresponding benzyl hydrocarbons through C-H and C-C bond cleavage has been developed. Mechanistic studies have shown that a DDQ-promoted cross-dehydrogenative coupling (CDC) reaction with subsequent oxidation and rearrangement are involved in this transformation.

Iron-catalyzed C-H and C-C bond cleavage: A direct approach to amides from simple hydrocarbons

Something functional: The title reaction proceeds in the presence of azide and water to deliver amides in high yields, and it can be used in a ring-expansion strategy to generate lactams. A mechanism is proposed based on experimental results. This reaction offers a new approach to functionalizing simple and readily available hydrocarbons.

Nucleophilic substitution reactions of cinnamoyl chlorides with anilines in acetonitrile and acetonitrile-methanol mixtures

Kinetic studies on the solvolysis (in MeOH-MeCN mixtures) and aminolysis (with anilines in MeCN) of cinnamoyl chlorides have been carried out at 25.0 deg C.The relatively large negative values of ρY+ = -0.9 ca. -1.5 for the methanolysis are consistent with a dissociative SN2-like mechanism.For the aminolysis, the ρy values are positive (ρY = 0.52 ca. 1.64) and ρX values range from -1.68 to -2.51 in acetonitrile.The positive values of βX = 0.6-0.9 and ρXY = 0.88 in acetonitrile, and isotope effect data suggest that the aminolysis proceeds by a stepwise mechanism with rate-limiting breakdown of the tetrahedral intermediate, T+/-.It is noted that in the acyl-transfer reactions proceeding by rate-limiting departure of the leaving group from the tetrahedral intermediate the signs of both ρY and ρXY are positive and the reactivity-selectivity principle (RSP) is valid in general.
