Yeni pirazolin türevlerinin sentezi ve yapı karakterizasyonu

Pyrazolines, which are nitrogen including five-membered heterocyclic structures, have been used in the organic and pharmaceutical industries. This study aimed was to synthesize characterizes new series of 3,5-diphenyl-4,5-dihydro-1H-pyrazole derivatives. The pyrazoline compounds synthesized from chalcones hydrazine hydrate two steps. In first step, were 2-amino acetophenone various substituted benzaldehyde by Claisen-Schmidt condensation at room temperature. second starting derivatives with glacial acetic acid anhydrous ethanol six novel utilizing intramolecular Michael addition reaction good yields. structures newly identified via 1H NMR, 13C FT-IR, HRMS.
