چکیده
In the title compound, C17H17N3O3S, the cyclo-pentane ring is disordered over two sets of sites with an occupancy ratio of 0.775 (8):0.225 (8) for the affected atoms. The thia-zolidinyl ring is planar (r.m.s. deviation = 0.024 Å) and forms a dihedral angle of 65.13 (8)° with the attached phenyl ring. The mol-ecular packing is stabilized by C-H⋯O and C-H⋯π inter-actions, forming a three-dimensional structure.

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].

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, C20H17N3O4S, all non-H atoms, except those of the phenyl ring, are approximately coplanar [maximum deviation = 0.2214 (1) Å], and the dihedral angle between their best plane and the benzene ring is 53.13 (1)°. A short intra-molecular O⋯S contact of 2.838 (1) Å is formed between the ester carbonyl O atom and the S atom of the thia-zolidine ring. In the crystal, mol-ecules ...

In the title compound, C(21)H(17)FN(4)O(2)S, the planar indole fused-ring [maximum deviation 0.009 (1) Å] makes dihedral angles of 54.75 (9) and 14.90 (9)°, respectively, with the phenyl ring and the dihydro-thia-zolyl ring. The -CH2CH=CH(2) substituent is disordered over two positions in a 0.51 (1):0.49 (1) ratio. An intra-molecular N-H⋯S hydrogen bond generates an S(5) ring motif. The two ind...
