چکیده

The title compound, C20H24N2O4, is the product of a ring-expansion reaction from a seven-membered hexa-hydro-azepine to a nine-membered azonine. The azonine ring of the mol-ecule adopts a chair-boat conformation. In the crystal, mol-ecules are linked by bifurcated N-H⋯(O,O) hydrogen bonds, generating [010] zigzag chains. The title compound shows inhibitory activity against acetyl-cholinesterase and butyrylcholinesterase, and might be considered as a candidate for the design of new types of anti-Alzheimer's drugs.
