N-alquilação regiosseletiva de pirazóis empregando 4-alcóxi(amino)-5-bromo-1,1,1-trifluorpent-3-en-2-onas
(Universidade Federal de Santa Maria, 2016-08-19)
This work presents the synthesis of three new series of nitrogen-heterocycles containing the substituent trifluoromethyl, exploiting the synthetic versatility and regioselectivity of 4-alkoxy-5-bromo-1,1,1-trifluorpent-3-en-2-ones ...
Síntese regiosseletiva de novas (4,5-diidropirazol-1-il)(-pirimidin-4-il)metanonas com potencial farmacológico
(Universidade Federal de Santa Maria, 2016-10-20)
This study shows the synthesis of five new 6-substituted 2-methylthio-4-pyrimidine carbohydrazides, aryl groups having such substituents (Ph, 4-FC6H4, 4-BrC6H4, 4-MeC6H4, 4-MeOC6H4) from the nucleophilic substitution of ...
