(E,E)-Methyl 2-[(3-nitrobenzylidene)aminomethyl]-3-phenylpropenoate
The mol-ecule of the title compound, C(18)H(16)N(2)O(4), adopts a T-shaped conformation with E stereochemistry for the imine double bond. The (3-nitro-benzyl-idene)amino fragment is almost planar, the mean planes of phenyl ring and nitro group forming a dihedral angle of 8.9 (3)°. In the 3-phenyl-acryloyl unit, the acrylic ester fragment is also almost planar, with the phenyl ring twisted by 41...
متن کاملSyntheses of highly functionalised 6-substituted pteridines.
Methods for the synthesis of polyfunctional 6-substituted pteridines from the corresponding 6-aldehydes are described. Alkene, ester, ketone, amide, cyano, oxime, bromo, methoxy and dihydroxy functional groups have all been introduced principally through improved methodologies for Wittig reactions using 2-thioalkyl-6-formylpteridines as substrates. Further modification of the alkenes derived fr...

Bacterial cell-to-cell communication (‘quorum sensing’) is mediated by structurally diverse, small diffusible signal molecules which regulate gene expression as a function of cell population density. Many different Gramnegative animal, plant and fish pathogens employ Nacylhomoserine lactones (AHLs) as quorum sensing signal molecules which control diverse physiological processes including biolum...
متن کاملThe total syntheses of basiliolide C, epi-basiliolide C, and protecting-group-free total syntheses of transtaganolides C and D.
The total syntheses of basiliolide C and previously unreported epi-basiliolide C are achieved by an Ireland-Claisen/Diels-Alder cascade. The development of a palladium catalyzed cross-coupling of methoxy alkynyl zinc reagents allows for the protecting-group-free syntheses of transtaganolides C and D. Syntheses of transtaganolides C and D are accomplished in a single operation to generate three ...
متن کامل3-Methylbenzo[1,2-c:5,4-c′]dichromen-6(8H)-one
The title compound, C21H14O3, crystallizes with eight independent mol-ecules (A-H) in the asymmetric unit which are arranged in four groups of two mol-ecules each (AB, CD, EF and GH). In each mol-ecule, the pyran-2-one ring is planar (r.m.s. deviations vary from 0.001 to 0.017 Å), while the pyran ring has a screw-boat conformation. In the crystal, mol-ecules stack in two columns, along the [10-...
