Synthesis of N-alkylated derivatives of pyrazolo[1,5-a]-pyrimidine and their reaction with methylamine

With the object of studying the factors influencing the course of enamine rearrangements, we have carried out the N-alkylation of alkyl- and aryl-substituted pyrazolo[1,5-a]pyrimidines. Using the NOEDIF NMR spectroscopic method for the cases of 5,7-dimeth

Synthesis of 5,7-diarylpyrazolo[1,5-a]pyrimidines via KOH mediated tandem reaction of 1H-pyrazol-3-amines and chalcones

An efficient and facile protocol has been developed for the synthesis of pyrazolo[1,5-a]pyrimidines through the tandem reaction of 3-aminopyrazoles and chalcones in the presence of catalytic amounts of KOH. The reported method offers access to 5,7-diarylp

Pyrazolopyrimidines based on 5-aminopyrazoles unsubstituted at the position 1

By condensation of various symmetric β-diketones with a series of 5-aminopyrazoles that are unsubstituted at the position 1, we have obtained a series of pyrazolo[1,5-a]pyrimidines that are of interest as physiologically active compounds. Hexafluoroacetylacetone reacts in another direction, forming pyrazolo[4,5-b]pyridine.
