Abstract: The current study presents the synthesis of functionalized pyrazoles (18–29) through 3 + 2 annulation reaction of ethyl 2-(arylidene)-3-oxobutanoates (8–13) with phenylhydrazine hydrochlorides (14–17) in acetic acid under reflux conditions. Stru

Golden section: A novel synthetic strategy for the synthesis of tetrasubstituted pyrazoles is provided. In an efficient C-C/N-N bond-formation cascade, enamines and nitriles are oxidatively coupled to deliver pyrazoles in good yields (see scheme). The rea

The reaction of 2-(1-alkoxyethylidene) 1,3-dicarbonyl compounds with hydrazine, phenylhydrazine, urea, and dimethylhydrazine leads to high yields of the corresponding functionally substituted pyrazoles, pyrimidines, and enehydrazines.
