Abstract

The title compound 1'-Benzyl-8-(4-fluorobenzyl)-8-azaspirobicyclo3.2.1]octane-3,4'-im idazolidine]-2',5'-dione, C(23)H(23)FN(3)O(2) is synthesized and the structure is investigated by X-ray diffraction studies. The compound crystallizes in the triclinic crystal class in the P1 space group. The hydantoin ring adopts a planar conformation and is affected by the p conjugation. The pyrrolidine and piperidine rings in the bicyclo octane moiety adopt envelope and chair conformations respectively. The structure exhibits both inter-and intramolecular hydrogen bonds of the type N-H center dot center dot center dot O, C-H center dot center dot center dot O, and C-H center dot center dot center dot N. The oxygen atom in the hydantoin ring simultaneously accepts two hydrogen bonds to form a three-centered hydrogen bonding pattern.
