Ethyl 4-methyl-1,3-dioxo-1,2,3,4-tetra-hydro-isoquinoline-4-carboxyl-ate.

ABSTRACT: In the title compound, C(13)H(13)NO(4), the fused-ring system is nearly planar, with an r.m.s. deviation of 0.0408 Å. In the crystal, mol-ecules are linked into centrosymmetric dimers by a pair of N-H⋯O hydrogen bonds. The ethyl group is disordered over two positions in a ratio of 0.758 (6):0.242 (6).

Ethyl 4-(1,3-benzodioxol-5-yl)-6-methyl-2-sulfanylidene-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.

Project description:In the title compound, C(15)H(16)N(2)O(4)S, the dihedral angles between the planes of the benzodioxole and ester groups and the plane of the six-membered tetra-hydro-pyrimidine ring are 89.5 (1) and 20.2 (1)°, respectively. Inter-molecular N-H⋯S hydrogen bonds assemble the mol-ecules into dimers, which are further connected via N-H⋯O inter-actions into chains parallel to [010]. Weak C-H⋯S and C-H⋯π inter-actions enhance the stability of the crystal structure.

Project description:In the title compound, C(23)H(21)NO(3)S, the piperidine ring of the tetra-hydro-isoquinolinone unit adopts a screw-boat conformation.
