Crystal and Molecular Structure Studies of Ethyl 4-(4-Hydroxyphenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate and Ethyl 4-(3-Bromophenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate

The crystal and molecular structures of the title compounds, ethyl 4-(4-hydroxyphenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate (I) and ethyl 4-(3-bromophenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate (II), are reported and confirmed by single crystal X-ray diffraction data. Compound (I), C26H24O5, crystallizes from a methanol solution in the monoclinic C2/c ...

Ethyl 5-(4-Bromophenyl)-4-methyl-1H-pyrrole- 2-carboxylate

This note describes a sequence converting an oxime-substituted pyrrolidine into a trisubstituted pyrrole structure. The synthetic route is based on a double chlorination of the pyrrolidine substrate followed by the base induced formation of both an imine and a nitrile oxide functionality. The latter reacts with an immobilized thiourea to yield an isothiocyanate which upon elimination generates ...

Ethyl 6-r-(2-chlorophenyl)-2-oxo-4-phenyl­cyclohex-3-ene-1-t-carboxylate

In the title mol-ecule, C(21)H(19)ClO(3), the cyclo-hexene ring adopts an envelope conformation, with all substituents equatorial. The plane through its five coplanar atoms makes dihedral angles of 12.75 (14) and 74.16 (8)° with the phenyl and benzene rings, respectively. The dihedral angle between the latter two rings is 81.73 (12)°. Inter-molecular C-H⋯O hydrogen bonds and intra-molecular C-H...

(±)-Ethyl 6-(6-meth­oxy-2-naphth­yl)-4-(4-methyl­phen­yl)-2-oxocyclo­hex-3-ene-1-carboxyl­ate

In the title compound, C(27)H(26)O(4), the dihedral angle between the naphthalene ring system and the benzene ring is 73.10 (5)°. In the crystal, a weak C-H⋯O inter-action occurs. Two C-H groups of the cyclo-hexene ring are disordered over two sets of sites in a 0.796 (5):0.204 (5) ratio, which corresponds to partial overlap of the two enanti-omeric mol-ecules.

In the title compound, C(22)H(21)ClO(4), the cyclo-hex-3-ene unit adopts an envelope conformation in both independent mol-ecules comprising the asymmetric unit. The two benzene rings are inclined to each other at a dihedral angle of 82.03 (5)° [86.37 (5)°]. In the crystal, the molecules interact via C-H⋯O, C-H⋯Cl and C-H⋯π interactions.
