The title compound, C 26 H 25 NO 3 , was synthesized by the 1,3dipolar cycloaddition reaction of benzaldehyde, -bromoacetophenone and N-benzylideneglycine ethyl ester. In the molecule, the heterocyclic five-membered ring adopts an envelope conformation.
In the title compound, C 22 H 28 N 2 O 2 S, the carbonyl group closer to the thiol group is almost perpendicular to the attached benzene ring. The crystal packing is stabilized by intermolecular N-HÁ Á ÁO and C-HÁ Á ÁO hydrogen bonds.
In the title compound, C 26 H 36 N 2 O 3 S, the amide bearing the N-S bond has an s-cis conformation, whereas that bearing the N-tert-butyl group has an s-trans conformation, the N-N-C O torsion angles being À15.1 (2) and À174.3 (2) , respectively. The steric size of the N-tert-butyl group causes th
