A highly efficient synthesis of hydantoins has been developed from simple and commercially available 1,3-dicarbonyl compounds, ureas, methyl ketones or terminal aryl alkenes. This protocol involves a sustainable integration two coupled domino processes: iodine-promoted unsymmetrical 1,4-enediones (domino I) the sequential transformation into II).
A highly efficient synthesis of unsymmetrical 1,4-enediones from 1,3-dicarbonyl compounds and methyl ketones or terminal aryl alkenes has been developed via a focusing domino strategy. Simple readily available starting materials, mild reaction conditions, very simple operation are advantages the reaction, which allow straightforward variety 1,4-enediones.
The sustainable byproduct catalyzed domino strategy has been performed for the facile synthesis of α-formyloxy and acetoxy ketonesviaiodination/nucleophilic substitution/hydrolyzation/oxidation sequences from simple readily available aromatic ketones/unsaturated methyl ketones.
A copper-catalyzed domino synthesis of 4H-pyrido[1,2-a]pyrimidin-4-ones has been developed from 1,4-enediones and 2-aminoheterocycles with air as the oxidant.
A highly efficient method for the construction of 3a,6a-dihydrofuro[2,3-b]furan derivatives has been developed via a novel bicyclization, which is very valuable synthesis fused furofuran compounds since it time-saving and catalyst-free. Based on coupled domino strategy to directly construct from methyl ketones.
Reports suggest that Bacillus spp. can be used to increase plant growth and resistance disease, but the molecular mechanisms underlying interaction between is not completely understood. In present study, clarify these mechanisms, cereus rice was investigated using two‐dimensional gel electrophoresis. Through comparative analysis, a total of 31 differentially expressed proteins were obtained upon B. NMSL88 treatment, including 22 up‐regulated nine down‐regulated. These data indicated certain...
An efficient procedure has been developed for the preparation of tetrasubstituted unsymmetrical 1,4-enediones via copper-promoted autotandem catalysis and air as oxidant. Various N-nucleophiles are compatible with this reaction, such morpholine, piperidine, pyrrolidine, arylamines, pyrazole, imidazole, benzimidazole, benzotriazole. This reaction also significant advantages in easily available substrates, atom economy, bond-forming efficiency, environmental benignity.
Although 2-imino-1H-imidazol-5(2H)-ones have important biological activities in metabolism, their synthesis has rarely been investigated. Quinoxalines as "privileged scaffolds" medicinal chemistry extensively investigated, but the development of novel and efficient synthetic methods remains very attractive. Herein, we developed two copper-catalyzed domino reactions for quinoxalines involving CC bond-cleavage with a 1,3-dicarbonyl unit leaving group. The sequence includes aza-Michael...
To investigate the decay mechanisms of red oak (Quercus rubra) and hemor (Schima spp.) woods in old architectural structure Xichuan Guild Hall, chemical composition changes were determined analyzed with X-ray photoelectron spectroscopy (XPS). The results showed that decaying resulted a noticeable decrease O/C from 0.59 to 0.42 wooden components. increase C1 contribution, C4 O1 O3 contributions, O2 contribution indicated carbohydrates components can be easily degraded by fungi compared...
A zinc(II) coordination polymer, [Zn4(o-bda)4(p-pbim)4] n (1) (p-pbim = 4-pyridylbenzimidazole, o-bda2− o-phenylenediacetic acid dianion), has been synthesized by hydrothermal method and characterized elemental analysis, IR, TG, photoluminescence X-ray single crystal diffraction.
