Synthesis and theoretical study of a new family of pyrazole derivative
(Elsevier B.V., 2024)
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 ...
Regiospecific synthesis of 5-trichloromethyl-1H-pyrazole and 1H-pyrazole-5-carboxylic ester derivatives
(BENTHAM SCIENCE PUBL LTD, 2008)
Reaction of 1,1,1-trichloro-4-methoxy-3-penten-2-one (1) with hydrazines (2a-h) (NH2NHR, R = H, Me, t-Bu, Ph, 4-NO2-C6H4, C6F5, CO2Me, CONH2) under differing conditions regiospecifically affords different pyrazole derivatives, ...

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 ...
Synthesis, characterization and DFT study of a new family of pyrazole derivatives

Wittig–Horner mediated synthesis of 4-vinyl sulfide derivatives of pyrazoles
(Pergamon-Elsevier Science Ltd, 2016-06)
The synthesis of a series of 4-vinyl sulfide derivatives of 1,3-diarylpyrazoles, including their corresponding sulfoxides and sulfones, is reported. Access to the target vinyl sulfides was stereoselectively achieved, in ...
