- Synthesis and Bioactivity of New Chalcone Derivatives as Potential Tyrosinase Activator Based on the Click Chemistry
Chao Niu, Gen Li, Adila Tuerxuntayi and Haji A. Aisa
Article first published online: 30 MAR 2015 | DOI: 10.1002/cjoc.201400820
A series of new chalcone derivatives which showed activator effect on tyrisinase were synthesized for the first time. Several compounds exhibited better activities than the control drug. Aftert that, the SAR of the compounds was summarized. Besides, several crystal structures of the compounds were got.
- Regioselective Oxidation Approaches to Concise Synthesis of (±)-Canabisin D
Wenling Li, Qian Liu, Hao Liu, Peilan Chen, Xi Yang and Yingying Liu
Article first published online: 30 MAR 2015 | DOI: 10.1002/cjoc.201500054
FeCl3·6H2O-catalyzed oxidative coupling reactions of feruloytyamide protected by tert-butyl or bromine group produced the desired 8-8-coupled aryldihydronaphthalene products, which underwent the debutylation or debromination to concisely synthesize (±)-canabisin D.
- Design, Synthesis and Herbicidal Activities of Tetrahydroisoindoline-1,3-dione Derivatives Containing Alkoxycarbonyl Substituted 2-Benzoxazolinone
Hao Zhang, Kechang Liu, Ruiquan Liu, Qibo Li, Yongqiang Li, Qingmin Wang and Shangzhong Liu
Article first published online: 30 MAR 2015 | DOI: 10.1002/cjoc.201500046
Two series of tetrahydroisoindoline-1,3-diones containing an alkoxycarbonyl substituted 2-benzoxazolinone moiety were designed and synthesized. Compound 1h displayed excellent herbicidal effect against Abutilon theophrasti with ED50 values of 1.8 g AI·ha−1, and compound 1h could potentially be used as a new post-emergence herbicide for maize fields.
- Effect of Different Ionic Liquids on 5-Hydroxymethylfurfural Preparation from Glucose in DMA over AlCl3: Experimental and Theoretical Study
Yan Yang, Wentao Liu, Ningning Wang, Haijun Wang, Wei Li and Zhanxin Song
Article first published online: 30 MAR 2015 | DOI: 10.1002/cjoc.201500030
A series of ionic liquids which possess the same cation and different anions were synthesized to explore the effect of anions on 5-hydroxymethylfurfural (HMF) preparation from glucose over AlCl3. Systematic experiments showed that N-methyl-2-pyrrolidone bromide ([NMP]Br) could promote selective conversion of fructose. Theoretical study indicated that Br− could also combine with Al3+, accelerating process of H-shift during glucose isomerization. This discovery can help us choose cocatalysts for low toxic metal, realizing selective conversion of cellulosic biomass conversion.
- Transfer Hydrogenation of Ethyl Levulinate to γ-Valerolactone Catalyzed by Iron Complexes
Nan Dai, Rui Shang, Mingchen Fu and Yao Fu
Article first published online: 30 MAR 2015 | DOI: 10.1002/cjoc.201500035
The conversion of biomass-derived ethyl levulinate to γ-valerolactone was realized efficiently by utilizing Casey's catalyst and isopropanol via catalytic transfer hydrogenation.
