(Z)-Ethyl 3-(2,4,6-trimethyl-anilino)but-2-enoate.

ABSTRACT: The title compound, C(15)H(21)NO(2), was obtained by the reaction of acetoacetate with 2,4,6-trimethyl-aniline using Mexican bentonitic clay as a catalyst. It crystallizes in the enamine form. The ?-enamino ester residue is almost perpendicular to the aromatic ring [dihedral angle = 88.10?(6)°]. The mol-ecular conformation is stabilized by a strong intra-molecular N-H?O hydrogen bond. In addition, the N-H group forms a weak inter-molecular N-H?O hydrogen bond linking the mol-ecules into centrosymmetric dimers.

The title compound, C(15)H(21)NO(2), was obtained by the reaction of acetoacetate with 2,4,6-trimethyl-aniline using Mexican bentonitic clay as a catalyst. It crystallizes in the enamine form. The β-enamino ester residue is almost perpendicular to the aromatic ring [dihedral angle = 88.10 (6)°]. The mol-ecular conformation is stabilized by a strong intra-molecular N-H⋯O hydrogen bond. In addition, the N-H group forms a weak inter-molecular N-H⋯O hydrogen bond linking the mol-ecules into centrosy  ...[more]
