Ethyl 4-(5-bromo-1H-indol-3-yl)-2,6,6-trimethyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylate
The title compound, C23H25BrN2O3, crystallizes with two independent mol-ecules in the asymmetric unit (Z' = 2) which differ in the twist of the 5-bromo-1H-indole ring with respect to the plane of the 4-methyl-1,4,5,6,7,8-hexa-hydro-quinoline ring [dihedral angles of 78.55 (9) and 89.70 (8)° in molecules A and B, respectively]. The indole ring is planar in both molecules [maximum deviations = 0....

In the mol-ecular structure of the title compound, C(21)H(25)NO(4), the dihydro-pyridine ring adopts a flattened boat conformation while the cyclo-hexenone ring is in an envelope conformation. In the crystal structure, mol-ecules are linked into a two-dimensional network parallel to (10) by N-H⋯O and O-H⋯O hydrogen bonds. The network is generated by R(4) (4)(30) and R(4) (4)(34) graph-set motifs.

In the title mol-ecule, C24H28N2O3, the cyclo-hexene ring is in a sofa conformation and the 1,4-dihydro-pyridine ring is in a slight boat conformation. In the indole ring system, the pyrrole and benzene rings form a dihedral angle of 2.63 (7)°. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules into C(6) chains parallel to the b axis and pairs of weak C-H⋯O hydrogen bonds link inversio...
متن کاملEthyl 4-acetyl-5-oxo-3-phenylhexanoate
The reaction of ethyl 3-bromo-3-phenyl-propano-ate with pentane-2,4-dione, in the presence of palladium(II) acetate and triphenyl-phosphine, in dimethyl-formamide, unexpectedly gave the title product, C(16)H(20)O(4). The mol-ecule contains one chiral C atom but the crystal is racemic. In the crystal, neighboring mol-ecules form a chain along [100] through three weak C-H⋯O inter-actions. Further...

In the title compound, C21H24BrNO4, the dihedral angle between the heterocyclic ring and the pendant aromatic ring is 80.20 (13)°. The hexahydroquinone [i.e. the one with the C=O group] ring adopts a sofa conformation. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. The ethyl group is disordered over two sets of sites with a refined site occupancy ratio of 0.633 (10):0.366 ...
