New Fluorinated Pyrazol and Uracil Derivatives: Synthesis and Biological Activity
(American Chemical Society Inc, 2009)
Both fluorinated pyrazoles and uracils are compounds that display very interesting biological activity. This chapter reviews recent work or our group in the development of synthetic strategies for the preparation of new ...
Improved Regioselectivity in Pyrazole Formation through the Use of Fluorinated Alcohols as Solvents: Synthesis and Biological Activity of Fluorinated Tebufenpyrad Analogs
(American Chemical Society, 2008-12)
The preparation of N-methylpyrazoles is usually accomplished through reaction of a suitable 1,3-diketone with methylhydrazine in ethanol as the solvent. This strategy, however, leads to the formation of regioisomeric ...
Key Intermediates: A simple and Highly Selective Synthesis of 5-amino-1-aryl-1H-pyrazole-4-carbonitriles for Applications in the Crop Protection
(Scientific Research Publishing, 2015-05)
A series of six pyrazoles was synthesized by Michael-type addition reaction. The molecules 5- amino-1-aryl-1H-pyrazole-4-carbonitrile (3a-f) were synthesized from (ethoxymethylene)malononitrile (1) and fluorinated and ...
Novel fluorinated curcuminoids and their pyrazole and isoxazole derivatives: Synthesis, structural studies, Computational/Docking and in-vitro bioassay
(Elsevier Science Sa, 2018-02)
In a continuing search for “curcuminoid (CUR) inspired” compounds with potential antitumor activity, a series of 21 new CUR-BF2 adducts and CURs bearing fluorine, trifluoromethylthio, trifluoromethoxy, and trifluoromethyl ...
Carbonyl complexes of copper(i) stabilized by bridging fluorinated pyrazolates and halide ions
(Royal Society of Chemistry, 2019)
Estudo de reações de flúor-inserção em 1h-pirazóis utilizando os reagentes fluorantes selectfluor, dast e mfsda
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2015-08-19)
This thesis describes the studies carried out using fluorinating reagents with different approaches: Selectfluor as an electrophilic fluorine source; DAST for nucleophilic fluorinations and MFSDA as a nucleophilic ...
Design, Synthesis and Insecticidal Activities of Novel Pirazol Derivatives to Crop Protection
(SCIENCEDOMAIN International, 2020)
Aryl pyrazoles are compounds that display very interesting biological activities. This chapter reviews recent work of our group in the development of synthetic strategies for the preparation of new examples of these kinds ...
Comparative study of biological activity of fluorinated 5- aminopyrazoles on Spodoptera frugiperda
(AD Publications, 2016-04)
Several derivatives aminopyrazoles, which are a new class of synthetic insecticide agents, have shown biological activity against lepidopteran, such as Spodoptera frugiperda. The aim of this work was to assess the biological ...
Isolable 1-Butene Copper(I) Complexes and 1-Butene/Butane Separation Using Structurally Adaptable Copper Pyrazolates
(Wiley-VCH Verlag, 2020-11-26)
Non-porous small molecule adsorbents such as {[3,5-(CF3)2Pz]Cu}3 (where Pz=pyrazolate) are an emerging class of materials that display attractive features for ethene−ethane separation. This work examines the chemistry of ...
Síntese de 5-hidróxi-3-(1,1-dimetoxietan-2-il)-5-trifluormetil-2-pirazolinas e 3-(1,1-difluoretan-2-il)-1H-pirazóis análogos
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2008-02-01)
This work describes, at first, the synthesis of 4,6,6-trimethoxy-1,1,1-trifluorohex-3-en-2-one by the acylation reaction of 1,1,3,3-tetramethoxybutane, in 65% yields.
Afterwards, the synthesis of a new series of ...
