Intra-molecular C-H⋯S contacts are present. In the crystal, inter-molecular N-H⋯N hy...

In the title compound, C17H15NO2S, the thia-zepine ring adopts a slightly distorted twist-boat conformation. The dihedral angle between the mean plane of the benzo-thia-zepin ring system and the benzene ring is 65.7 (1)°. In the crystal, pairs of N-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers, generating R2 (2) (8) ring motifs. These dimers are further linked by C-H⋯π and π-...

In the title thia-zolidine-4-one derivative, C20H21NO6S, the central thia-zolidine ring is essentially planar (r.m.s. deviation for all non-H atoms = 0.0287 Å) and forms a dihedral angle of 88.25 (5)° with the meth-oxy-substituted benzene ring and 74.21 (4)° with the 1,3-benzodioxole ring. The heterocyclic ring (with two O atoms) fused to benzene ring adopts an envelope conformation with the no...

There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(11)NO(4)S. The heterocyclic thia-zine rings in both mol-ecules adopt half-chair conformations with the S and N atoms displaced by 0.455 (4) and 0.254 (4) Å, respectively, in one mol-ecule, and 0.480 (4) and 0.224 (5) Å in the other, on opposite sides of the mean planes formed by the remaining ring atoms. The crystal s...

The title compound, C(10)H(14)N(2)O(4)S, was synthesized by the reaction of methyl 2-amino-thia-zole-5-carboxyl-ate and di-tert-butyl carbonate. In this structure, the thia-zole ring is planar (mean deviation = 0.0011 Å). Two weak intra-molecular C-H⋯O hydrogen bonds are formed between two of the methyl groups and one carbonyl O atom, resulting in the formation of two twisted six-membered rings...

In the crystal structures of the title compounds, C15H11Cl2NOS, (1), and C15H11Cl2NO2S, (2), wherein (2) is the oxidized form of (1), the thia-zolidine ring is attached to two chloro-phenyl rings. The chloro-phenyl ring on the 2-carbon atom position points in the same direction as that of the S atom in (1), while in (2), the S atom points in the opposite direction. The O atom on the chiral S at...
