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
Nam,Grandberg,Sorokin
, p. 1371 - 1374 (2007/10/03)
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.
