In the title compound, C(11)H(12)N(2)O(3)S, the methyl acetate and benzoyl groups adopt a cis-trans configuration with respect to the thiono S atom across the C-N bonds. An intra-molecular N-H⋯O hydrogen bond is observed. In the crystal packing, mol-ecules are linked by inter-molecular N-H⋯S and C-H⋯O hydrogen bonds to form a two-dimensional network lying parallel to (101).

In the mol-ecule of the title compound, C(8)H(7)NO(5), the acetate group is oriented with respect to the aromatic ring at a dihedral angle of 85.30 (3)°. An intra-molecular O-H⋯O hydrogen bond results in the formation of a non-planar six-membered ring, adopting an envelope conformation. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules.

In the title compound, C(14)H(18)N(2)O(3)S, the butyl acetate fragment and the benzoyl group adopt a cis-trans configuration, respectively, with respect to the thiono S atom across the C-N bonds. In the crystal packing, the mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds to form a one-dimensional chain along the c axis. The terminal butyl C atom is disordered with occupa...
