Aminoazoles in Heterocycles Synthesis: II. * Trifluoromethyl-containing Diketones in the Synthesis of Pyrazolo(1,5-a)pyrimidines
TL;DR: In this article, a regioselective synthesis was carried out of 7-trifluoromethylpyrazolo[1,5-a]pyrimidines by reaction of 3(5)aminopyrazoles with 1,3-diketones containing CF3 group.

α-aminoazoles in synthesis of heterocycles: III. 4-trifluoromethylpyrazolo[3,4- b ]pyridines: Synthesis and structure
TL;DR: In this paper, the regiostructure of regioisomeric pyrazolo[3,4-b]pyridines was proved by 1H and 13C NMR homo- and heteronuclear correlation spectroscopy.

TL;DR: In this paper, a procedure was proposed for the synthesis of 7-trifluoromethylazolo[1,5-a]pyrimidines by reactions of 2-ethoxyvinyl trifluorsyl ketones and 2,2-diethoxyvinyl trifeldioxyl ketone with 5(3)-aminoazoles.

α-Amino azoles in the synthesis of heterocycles: VI. Synthesis and structure of cycloalkane-annulated pyrazolo[1,5-a]pyrimidines
TL;DR: In this paper, reaction of 4-aryl-1H-pyrazol-5(3)-amines with 2-acylcycloakanones (acyl-5,5-dimethylcyclohexane-1,3-diones) led to the formation of regioisomeric 6,7,8,9-tetrahydropyrazolo[1,5,a]quinazoline, 5,6, 7,8-dihydro-6H-cyclopenta[e]pyrazolo]

α-aminoazoles in synthesis of heterocycles: IV. Regiodirection of 3(5)-amino-5(3)-methylpyrazole reaction with hexafluoroacetylacetone
TL;DR: In this article, the reaction of 3(5)-amino-5(3)-methylpyrazole with hexafluoroacetylacetone depending on the process conditions led to the formation either of pyrazolo[1,5-a]pyrimidine or pyrazol[3,4-b]-pyridine.
