Fungicidal Properties of Some Novel Trifluoromethylphenyl Amides

Trifluoromethylphenyl amides (TFMPAs) were designed and synthesized as potential pesticides. Thirty-three structures were evaluated for fungicidal activity against three Colletotrichum species using direct bioautography assays. Active compounds were subsequently tested against C. fragariae, C. gloeosporioides, C. acutatum, Phomopsis obscurans, P. viticola, Botrytis cinerea and Fusarium oxysporum. The study identified 2-chloro-N-[2,6-dichloro-4-(trifluoromethyl)phenyl]acetamide (7a) as showing the strongest antifungal activity, and the broadest activity spectrum in this set against Colletotrichum acutatum (at 48 and 72 h) and Phomopsis viticola (at 144 h). The presence of triethylamine in its complex with N-[2,6-dichloro-4-(trifluoromethyl)phenyl]-2,2,3,3,3-pentafluoropropanamide (7b′) played an important role in the bioactivity, and depending on the concentration or fungal species it showed higher or lower activity than the parent amide. X-Ray crystallography has shown that the complex (7b′) is an ion pair, (C10H2Cl2F8NO)? (C6H16N)+, where a proton is transferred from the amide nitrogen to the triethylamine nitrogen and then connected by hydrogen bonding to the acyl oxygen (N?H 0.893 ?; H???O 1.850 ?; N???O 2.711 ?; N?H???O 161.2(13)°). Although none of these compounds were better than standards, this work revealed some potential lead structures for further development of active novel compounds.

Visible-light-induced Pd-catalyzed: Ortho -trifluoromethylation of acetanilides with CF3SO2Na under ambient conditions in the absence of an external photocatalyst

A visible-light-induced Pd-catalyzed ortho-trifluoromethylation of acetanilides with CF3SO2Na was developed. The reaction proceeded smoothly at room temperature in air without any external photocatalyst or additive, providing the desired products in moderate to good yields with good functional group tolerance and regioselectivity.

Quinoline-3-carboxamides

Novel quinoline-3-carboxamides of the formula STR1 wherein R1 is in the 5,6,7 or 8-position and is selected from the group consisting of hydrogen, halogen, --CF3, --OCF3, --SCF3, straight chain alkyl of 1 to 4 carbon atoms, branched alkyl of 3 to 5 carbon atoms and alkoxy of 1 to 4 carbon atoms, R2 is selected from the group consisting of hydrogen and methyl, R3 is selected from the group consisting of thiazolyl, 4,5-dihydrothiazolyl, pyridinyl, oxazolyl and imidazolyl and R4 is selected from the group consisting of hydrogen, hydroxyl, alkyl of 1 to 4 carbon atoms, phenyl and benzyl with the proviso that when R1 is in the 7 or 8-position and is halogen, --CH3, --OCF3 or --SCF3 and R4 is hydrogen, R3 is not thiazolyl, pyridinyl or oxazolyl and the non-toxic, pharmaceutically acceptable acid addition salts when R3 is imidazolyl or 4,5-dihydrothiazolyl having analgesic activity and their preparation and novel intermediates therefore.
