In this work, a synthesis of pyrazoline nucleosides analogues is presented, using the stereospecific sodium salt glycosylation procedure. In the first step, chalcones were prepared using Claisen Schmidt reaction by reacting benzaldehyde with enolizable ketones in ethanolic NaOH solutions. Next, these chalcones were immediately reacted with hydrazine hydrochloridein the presence of dry methanol to obtain the corresponding 2-pyrazolines. Finally, the coupling of the pyrazolines with 1-chloro-arabinofuranose leads to different β-nucleosides as the major product (13-17) in good yields. The structures of these derivatives were characterized by infrared and 1HNMR spectroscopy and mass spectrometry.

The title diamines were prepared according to von Auwer's/Arakawa's procedures starting from appropriately substituted benzaldehydes and actophenones via chalcones, addition of two moles of hydroxylamine, reduction, and separation of diastereomers as N,N'-bisacetamides. - The Pt(II) complexes of the title ligands are described in the following paper.
