A versatile method for the rapid synthesis of diverse functionalized pyrazolines has been developed based on copper-mediated aminofunctionalization β,γ-unsaturated hydrazones. The scope this strategy encompasses a range difunctionalization reactions: aminoazidation, aminohalogenation, and aminothiocyanation. These reactions provide straightforward access to series useful pyrazoline building blocks containing various functional groups that are hard traditionally.
