摘要: Abstract Pyrazoline is an important heterocyclic compound in organic and pharmaceutical industry. The pyrazoline-based compounds are intensively used medicines agricultural This review to highlight various synthesis of pyrazolines namely azo-pyrazolines, bis-pyrazoline, symmetrical asymmetrical via one-pot two-pot synthetic techniques. One-pot technique unique method for direct reaction α, β-unsaturated aldehydes acetophenones with hydrazines. While more commonly reported the formation chalcone prior pyrazoline. significant field related industries.
