Hydrogen-bonded supramolecular structures of three related 4-(5-nitro-2-furyl)-1,4-dihydropyridines.
In ethyl 5-cyano-2,6-dimethyl-4-(5-nitro-2-furyl)-1,4-dihydropyridine-3-carboxylate, C15H15N3O5, the molecules are linked into chains by a single N-H...O hydrogen bond. The molecules in diethyl 2,6-dimethyl-4-(5-nitro-2-furyl)-1,4-dihydropyridine-3,5-dicarboxylate, C17H20N2O7, are linked by a combination of one N-H...O hydrogen bond and two C-H...O hydrogen bonds into sheets built from equal nu...
متن کاملHydrogen bonding in nitroaniline analogues: hydrogen-bonded sheets in 2-amino-4,6-dimethoxy-5-nitropyrimidine and pi-stacked hydrogen-bonded sheets in 4-amino-2,6-dimethoxy-5-nitropyrimidine.
In 2-amino-4,6-dimethoxy-5-nitropyrimidine, C(6)H(8)N(4)O(4), the molecules are linked by one N-H...N and one N-H...O hydrogen bond to form sheets built from alternating R(2)(2)(8) and R(6)(6)(32) rings. In isomeric 4-amino-2,6-dimethoxy-5-nitropyrimidine, C(6)H(8)N(4)O(4), which crystallizes with Z' = 2 in P-1, the two independent molecules are linked into a dimer by two independent N-H...N hy...
متن کاملSynthesis and Antibacterial Evaluation of (S,Z)-4-methyl-2-(4-oxo-5- ((5-substituted phenylfuran-2-yl) methylene)-2-thioxothiazolidin-3-yl) Pentanoic Acids
The resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. Infection of drug-resistance bacteria seriously threatens human health. Currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. In this paper, a series of (S,Z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...

متن کاملSynthesis and structural determination of novel 5-arylidene-3-N(2-alkyloxyaryl)-2-thioxothiazolidin-4-ones.
As part of our project devoted to the synthesis of heterocycles including thiazole rings, some new 5-arylidene-2-thioxo-3-N-arylthiazolidin-4-ones were synthesized by Knoevenagel condensation. An interesting feature of these compounds is that their chirality is induced by that of their 3-N-(2-alkyloxyaryl)-2-thioxothiazolidin-4-one precursors, which in turn is due to the presence of a C2 axis o...
