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 ...
متن کاملEthyl 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 ...
متن کاملEthyl 6-(4-methoxyphenyl)-2-oxo-4-phenylcyclohex-3-enecarboxylate
The asymmetric unit of the title compound, C(22)H(22)O(4), consists of two independent mol-ecules (A and B). The cyclo-hexene rings adopt slightly distorted sofa conformations in both mol-ecules. The dihedral angles between the benzene rings are 74.16 (13) and 71.85 (13)° in mol-ecules A and B, respectively. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into a ribbon-like struct...

In the crystal of the title compound, C(10)H(12)BrNO, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Further N-H⋯O hydrogen bonds link the dimers into sheets propagating in (100).
متن کاملSYNTHESIS AND PHARMACOLOGICAL EVALUATION OF 6-CARBETHOXY-5-(3'-BROMOPHENYL)-3-ARYL-2-CYCLOHEXENONES AND 6-ARYL-4-(3'-BROMOPHENYL)-3-OXO-2,3A,4,5-TETRAHYDRO-2H-INDAZOLES
6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...
