Synthesis, structure, and biological activity of 3,5,5′-trioxospiro[pyrazolidine-4,2′-pyrrolidine]-4′-carbohydrazides
摘要
Spiroheterocyclic compounds, (3′R*,4′ S*)-3′-(het)aryl-3,5,5′-trioxospiro[pyrazolidine-4,2′-pyrrolidine]-4′-carbohydrazides, were synthesized by the reaction of diastereopure trimethyl (3R*,4S*)-1-acetyl-4-(het)aryl-2-pyrrolidone-3,5,5-tricarboxylates with hydrazine hydrate. The structures of the synthesized compounds were confirmed by spectral methods and X-ray diffraction analysis. Some of the new compounds were found to exhibit anxiolytic and antidepressant activity.
