One-pot synthesis is an active topic in organic chemistry due to its intrinsic advantages of
simple operation, high mass efficiency, low cost, and less amount of waste disposal. Among …

Three types of trifluoromethylated pyrazolidines, pyrazolines, and pyrazoles can be
synthesized via divergent reaction of β-CF3-1, 3-enyne with hydrazines. The reaction with …

Abstract A new series of 1, 3, 5-trisubstituted 2-pyrazoline derivatives (3a–l) are synthesized
in good to excellent yields from the corresponding chalcones (1a–h) and acid hydrazides …

The synthesis of pyrazole derivative using α, β‐unsaturated carbonyl compounds has
attracted increasing attention of the synthetic organic chemist community. Interestingly, the …

A series of novel isoniazid pyrazole derivatives were synthesized by an efficient,
multicomponent reaction of various substituted aromatic aldehydes, isoniazid, and …

This research included the preparation of new pyrazoline rings from chalcones of the 1, 3-
benzodiaoxolo ring with hydrazine and some of its derivatives, In the first step: new …
