Methyl 3′,4′,5′-trimeth­oxy­biphenyl-4-carboxyl­ate

In the title compound, C17H18O5, the dihedral angle between the benzene rings is 31.23 (16)°. In the crystal, the mol-ecules are packed in an anti-parallel fashion in layers along the a axis. In each layer, very weak C-H⋯O hydrogen bonds occur between the meth-oxy and methyl ester groups. Weak C-H⋯π inter-actions between the 4'- and 5'-meth-oxy groups and neighbouring benzene rings [meth-oxy-C-...

Design, Synthesis and Anti-Tubercular Activity of Novel 1, 4-Dihydropyrine-3, 5-Dicarboxamide Containing 4(5)-Chloro-2-Ethyl-5(4)-Imidazolyl Moiety

Current researches have showed that N3, N5-diaryl-2, 6-dimethyl -1, 4-dihydropyrine-3, 5- dicarboxamide analogues demonstrate notable anti-tubercular activity. In this study, Hantzsch condensation was used to design and synthesize new analogues of dihydropyridine (DHP). Different diary carboxamides were inserted at positions 3 and 5 of the DHP ring. 4(5)-chloro-2-ethyl-5(4)-imidazolyl moiety wa...
