Tandem Thermal Reactions for the Synthesis of Jasmonoids
Journal of the Chinese Chemical Society - Tập 45 Số 2 - Trang 319-321 - 1998
Tse‐Lok Ho, K. F. Shyu
AbstractA tandem reaction tactic for the preparation of a jasmonoid intermediate consists of pyrolysis of a spiroannulated cyclopentanone. The thermal decomposition actually involves a retro‐Diels‐Alder reaction and a homo‐1,5‐hydrogen shift with cleavage of the cyclopropane unit.
Spectroscopic Characterization of Some Tetradentate Schiff Bases and Their Complexes with Nickel, Copper and Zinc
Journal of the Chinese Chemical Society - Tập 48 Số 2 - Trang 153-158 - 2001
Mokhles M. Abd‐Elzaher
AbstractThree ligands have been formed by the 1:2 molar condensation of o‐phenylenediamine with salicyldhyde, 2‐hydroxy‐1‐naphthaldhyde or o‐hydroxyacetophenone. The potentially tetradentate ligands are N,N′‐bis(salicyldhyde)‐o‐phenylenediamine(SalophH2), N,N′‐bis(2‐hydroxy‐1‐naphthaldhyde)‐o‐phenylenediamine (NophH2) and N,N′‐bis(o‐hydroxyacetophenone)‐o‐phenylenediamine (AophH2), respectively.

Ionic Liquid as an Efficient Promoting Medium for Synthesis of Bis‐Pyrazolo[3,4‐b:4′,3′‐e]Pyridines
Journal of the Chinese Chemical Society - Tập 55 Số 4 - Trang 755-760 - 2008
Daqing Shi, Fang Yang
AbstractThe preparation of a series of bis‐pyrazolo[3,4‐b:4′,3′‐e]pyridines by the reaction of 5‐aminopyrazole with aldehydes in ionic liquid [bmim]Br is described. This new method has the advantages of easier work‐up, milder reaction conditions, high yields and environmental friendliness compared with other methods.
Synthesis of (3,5‐Aryl/methyl‐1H‐Pyrazol‐1‐yl)‐(5‐Arylamino‐2H‐1,2,3‐Triazol‐4‐yl)Methanone
Journal of the Chinese Chemical Society - Tập 55 Số 4 - Trang 761-767 - 2008
Ziping Cao, Bin Quan, Heng‐Shan Dong
AbstractSome new (3,5‐aryl/methyl‐1H‐pyrazol‐1‐yl)‐(5‐arylamino‐2H‐1,2,3‐triazol‐4‐yl)methanones were synthesized and characterized by 1HNMR, 13C NMR, MS, IR spectra data and elemental analyses or high resolution mass spectra (HRMS). During the procedure, Dimroth rearrangement was used in this synthesis.
The One‐Pot Synthesis of 2,4,5‐Triaryl‐Imidazoles Using Heteropolyacids as Heterogeneous and Recyclable Catalysts
Journal of the Chinese Chemical Society - Tập 55 Số 6 - Trang 1199-1203 - 2008
Majid Μ. Heravi, Samahe Sadjadi, Hossein A. Oskooie, Rahim Hekmatshoar, Fatemeh F. Bamoharram
Abstract2,4,5‐triaryl imidazoles were obtained in high yields with excellent purity from the condensation of benzaldehydes, NH4OAc and 1,2‐diketone in the presence of a catalytic amount of various heteropolyacids (HPAs).
Formation of a p‐n heterojunction photocatalyst by the interfacing of graphitic carbon nitride and delafossite CuGaO2
Journal of the Chinese Chemical Society - Tập 69 Số 7 - Trang 1042-1050 - 2022
B. Martı́nez, Dai‐Ning Chang, Yucheng Huang, Chung‐Li Dong, Te‐Wei Chiu, Ming‐Hsi Chiang, Chun‐Hong Kuo
AbstractPhotocatalysts have focused on scientific endeavors for five decades already. Their ability to generate solar fuel via relatively environmentally benign processes brings promises of a future with increasingly sustainable energy production. A class of materials, heterojunction (HJ) semiconductors, have immense potential due to their versatility, stability, and cost‐effectiveness. In additio... hiện toàn bộ
Constituents of the Heartwood of Diospyros Eriantha
Journal of the Chinese Chemical Society - Tập 41 Số 2 - Trang 195-198 - 1994
Chien‐Chih Chen, Hsi‐Jung Yu, Jun‐Chih Ou, Tzu‐Ming Pan
AbstractThe isolation and identification of fifteen compounds from the heartwood of Diospyros eriantha are described. Their structures were determined on the basis of spectral evidence and/or comparison with authentic samples. These compounds include three steroids (stigmast‐4‐en‐3‐one, stigmast‐4‐ene‐3,6‐dione, and 3β‐hydroxystigmast‐5‐en‐7‐one), seven triterpenoids (friedelin, lupeol, betulinald... hiện toàn bộ
Chemical synthesis of MnFe2O4/chitosan nanocomposites for controlled release of ofloxacin drug
Journal of the Chinese Chemical Society - Tập 66 Số 6 - Trang 600-607 - 2019
Ayoub Moghadam
In this study, we synthesized ofloxacin‐loaded MnFe2O4 nanoparticles (NPs) surface modified with chitosan (CS‐MnFe2O4) for prolonged antibiotic release in a controlled manner. It was found that the synthesized CS‐MnFe2O4 was spherical in shape with an average size of 30–50 nm, low aggregation, and good magnetic responsibility. An in vitro drug loading and release kinetics study reveals that the dr... hiện toàn bộ
The Isolation and Determination of Sulforaphane from Broccoli Tissues by Reverse Phase‐High Performance Liquid Chromatography
Journal of the Chinese Chemical Society - Tập 58 Số 7 - Trang 906-910 - 2011
Seyed Naser Azizi, Behnam Amiri-Besheli, Salman Sharifi‐Mehr
AbstractSulforaphane is a cognate isothiocyanate of glucoraphanin, released by degradation of glucosinolate through myrosinase enzyme, when Brassica tissues are crushed or chewed. C8 analytical column and mixture of water/acetonitrile 65/35 (ν/ν) as mobile phase were used to separate sulforaphane in broccoli tissues (e.g., 7‐day‐seedling, seed, floret and leave). Confirmation of sulforaphane in cr... hiện toàn bộ
Thermodynamic Studies on the Interaction of Cobalt with Alpha‐Amylase
Journal of the Chinese Chemical Society - Tập 45 Số 5 - Trang 667-671 - 1998
Ali Akbar Saboury, M. U. Dahot, Sirous Ghobadi, Jamshidkhan Chamani, Ali Akbar Moosavi‐Movahedi
AbstractThe interaction of α‐amylase from Bacillus amyloliquefaciens with divalent cobalt ion was studied by equilibrium dialysis and isothermal titration microcalorimetry methods at 27 °C in neutral solution at pH = 7.0. A new equation with a useful graphical method, very similar to the Scatchard plot was introduced to obtain a dissociation equilibrium constant using microcalorimetric data. The c... hiện toàn bộ
