Abstract:Uma série de novas pirazolinas N-acil trialometiladas derivadas de ésteres metílicos de ácidos graxos foi sintetizada por reação de ciclocondensação entre hidrazidas graxas e 4-alcóxi-1,1,1-trialometil-3-alquen-2-onas. Ciclizações eficientes e regioespecíficas catalisadas por BF 3 ·MeOH levaram aos produtos desejados em rendimentos de bons a excelentes e alto grau de pureza.A series of new fatty N-acyl trihalomethylated pyrazoline derivatives from fatty acid methyl esters was synthesized by the cyclocondensati… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
