Aminothiazole nuclei and their various derivatives have been long used as precursors for
the synthesis of biologically active molecules. As a typical heterocyclic amine, 2 …

Abstract A series of 1, 3, 4-thiadiazole derivatives were designed and synthesized using N-
(4-nitrophenyl) acetohydrazonoyl bromide and 1-[3, 5-dimethyl-1-(4-nitrophenyl)-1 H …

A large and valuable store of review literature on many aspects of the chemistry of
heterocyclic com-pounds has grown up over the last few decades. 1 However, the …

The reaction of hydrazino of pyrazolopyrimidine derivatives with N-phenyl-C-
acetylmethanohydrazonoyl chloride afforded the corresponding hydrazonoyl chlorides. The …

Two series of novel 3, 7-bis (arylazo)-2, 6-diphenyl-1H-imidazo [1, 2-b] pyrazoles were
prepared starting from N-aryl 2-oxo-2-phenylethanehydrazonoyl bromides. The acid …

As a continuation of our research on developing anticancer agents and based on the proven
proprieties of thieno [2, 3b] pyridines as anticancer, we have designed to synthesize novel …

This review summarizes the reactions of nitrilimines, genearted in situ by base-catalyzed
dehydrohalogenation of the respective hydrazonoyl halides, with aminoazoles, aminoazines …

Syntheses and reactions of 2-amino-4-substituted-1, 3-thiazoles are reviewed in a formal
way. The title compounds are most easily accessible by various approaches, and even …

Publisher Summary This chapter discusses the chemistry of pyrazoles condensed to
heteroaromatic five-and six-membered ring structures, and the synthesis of pyrazoloazines …
