چکیده
In the title compound, C(14)H(11)F(2)N(3)S, the heterocyclic five-membered ring has an envelope conformation. Although the mol-ecule is chiral, the compound is a racemate (R/S). There is a weak inter-molecular C-H⋯π inter-action but no classical hydrogen bonds are observed in the crystal structure.

The mol-ecule of the title compound, C26H24N4O7S, adopts a trans conformation about the central N-N bond, presumably to minimize steric between the substituents on these two atoms. An intra-molecular N-H⋯O hydrogen bond occurs. The phenyl ring is disordered over two sets of sites, with an occupancy ratio of 0.624 (8):0.376 (8). The azolidine ring is essentially planar [maximum deviation = 0.008...

In the title compound, C22H19N3O3S, the six-membered ring of the 1,2,3,4-tetra-hydro-naphthalene ring system adopts an envelope conformation with the central CH2 C atom as the flap. The mol-ecular conformation is stabilized by an S⋯O contact, forming a pseudo-five-membered ring. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along [102].
