In the title compound, C(10)H(9)NO(3), the mean plane through the acetate group forms a dihedral angle of 83.39 (5)° with the plane of the indole ring system. In the crystal, pairs of centrosymmetrically related mol-ecules are linked into dimers by N-H⋯O hydrogen bonds. The dimers are further connected into layers parallel to the bc plane by C-H⋯O hydrogen bonds.

The title compound, C(13)H(16)N(2)O(3)S, is a thio-urea derivative with benzoyl and propoxycarbonyl-methyl groups attached to the two terminal N atoms. These groups adopt trans and cis configurations, respectively, with respect to the S atom across the thio-urea C-N bonds. The compound crystallizes in the P2(1)/c space group with Z = 8, resulting in two unique molecules in the asymmetric unit l...

The title compound, C(12)H(14)N(2)O(3)S, adopts a cis-trans geometry of the thio-urea group and is stabilized by intra-molecular hydrogen bonds between the carbonyl O atoms and the H atom of the thio-amide group and by a C-H⋯S interaction. Mol-ecules are linked by two inter-molecular hydrogen bonds (C-H⋯O and N-H⋯O), forming a one-dimensional chain parallel to the c axis.

In the mol-ecule of the title compound, C(10)H(10)N(2)O(5), intra-molecular C-H⋯O inter-actions result in the formation of a five- and a six-membered ring. The five-membered ring is planar and is oriented at a dihedral angle of 0.34 (3)° with respect to the plane of the aromatic ring, while the six-membered ring has a twist conformation. In the crystal structure, inter-molecular C-H⋯O inter-act...
