First published: September 1, 1987
Abstract
Condensation reaction of the diaminopyrazole (I) with the olefinic derivatives (II), (IV), (VI), and the nitriles (VIII) yields the pyrazolopyrimidines (III), (V), (VII), and (IX) - (XI).
ChemInform Abstract
Condensation reaction of the diaminopyrazole (I) with the olefinic derivatives (II), (IV), (VI), and the nitriles (VIII) yields the pyrazolopyrimidines (III), (V), (VII), and (IX) - (XI). Similarly, the imidazopyrazole (XIII) is prepared from (I) and the hydrazonoyl chloride (XII).
