For anticancer cell line evaluation, a new sequence of pyrazolo [1-5a] pyrimidine and
imidazo [1, 2-b] pyrazole derivatives were synthesized. The reaction of 5-aminopyrazolo with …

A novel series of pyrazolo [1, 5-a] pyrimidine-3-carbonitriles substituted with 7-amino, 7-
substituted amino and 5-substituted amino groups was synthesized. Some of the newly …

A series of novel pyrazolo [1, 5‐a] pyrimidines were designed and synthesized in order to
find novel potent anti‐tumor compounds. The structures of all the compounds were …

ABSTRACT Some pyrazolo [3, 4-d] pyrimidines derivatives and their triazole derivatives
were synthesized starting from p-toluene sulfonyl hydrazide 1 by reaction with different …

A new series of pyrazole 4–7 and pyrazolo [1, 5-a] pyrimidine 8–13 were synthesized by
using a simple, efficient procedure, and screened for their in-vitro antimicrobial and …

A new series of pyrazolo [3, 4-d] pyrimidine-3-carbonitrile and pyrazolo [3, 4-b] pyridine-3-
carbonitrile derivatives was synthesized by the reaction of 5-amino-1-tosyl-1 H-pyrazole-3, 4 …

A novel series of pyrazolo [1, 5-a] pyrimidine substituted diamides has been designed and
synthesized using a linear mode multistep synthesis. The synthesized compounds were …

A novel series of pyrazoles and pyrazolo [1, 5-a] pyrimidines bearing benzothiazole moiety
were designed and synthesized. Chemical structures were confirmed by spectral data and …

A new library of different substituted aryl derivatives of isoxazole-pyrazolo [1, 5-a] pyrimidine
(10a–j) were prepared, confirmed their structures by 1HNMR, 13CNMR and mass spectral …

Abstract The key precursor E‐3‐(N, N‐dimethylamino)‐1‐(3‐methylthiazolo [3, 2‐a]
benzimidazol‐2‐yl) prop‐2‐en‐1‐one 4 was synthesized in good yield using Gold's reagent …
