Crystal structure of 2-[(5',6',7',8'-tetrahydro-5',5',8',8'-tetramethyl)-2'-naphthyl]-1-ethyl-1H-benzimidazole-5-carboxylic acid ethyl ester.
retinoids with a tetrahydronaphthalene structure (Fig. 1), was synthesized using an NaHSO3 addition product of 5,6,7,8tetrahydro-5,5,8,8-tetramethyl-2-naphthalene-carboxaldehyde (compound I) as a starting material, which was prepared as described.1 The condensation of compound I and 4-ethylamino3-amino-ethylbenzoate (mp: 73 ̊C) in DMF for 70 h gave the title compound (recrystallized from hexane/...
متن کاملEthyl 1,3-dimethyl-1H-indole-2-carboxylate
In the title compound, C(13)H(15)NO(2), the plane of the indole ring forms a dihedral angle of 5.26 (6)° with the ester group and the ethyl side-chain C atoms. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions.
متن کاملEthyl 3,4-dimethyl-1H-pyrrole-2-carboxylate
The non-H atoms of the title compound, C(9)H(13)NO(2), are almost coplanar (r.m.s. deviation = 0.0358 Å). Weak inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the b axis with graph-set motif C(5). The chains are further linked into a three-dimensional network by C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
متن کاملEthyl 3,5-dimethyl-1H-pyrrole-2-carboxylate
In the title compound, C(9)H(13)NO(2), there are two independent mol-ecules per asymmetric unit. The mol-ecules are very similar and almost planar, with the ethoxy-carbonyl group anti to the pyrrole N atom. The two independent mol-ecules are joined into dimeric units by strong hydrogen bonds between NH groups and carbonyl O atoms.
متن کاملCrystal structure of ethyl 2-(1H-benzimidazol-2-yl)-2-[2-(4-nitrophenyl)hydrazinylidene]acetate
The title compound, C17H15N5O4, was obtained via the condensation of 3-eth-oxy-2-[2-(4-nitro-phen-yl)hydrazono]-3-oxo-propanoic acid with 1,2-di-amino-benzene. In the mol-ecule, the dihedral angles between the acetate group and the two aromatic subunits (benzimidazole and nitro-phenyl-hydrazone) are 7.35 (9) and 18.23 (9)°, respectively. Intra-molecular N-H⋯O and N-H⋯N contacts occur. In the cr...
