Here we used a mouse model of zymosan-induced colorectal hypersensitivity, a similar model of IBS in our previous work, to evaluate the effectiveness of the different number of times of acupuncture and elucidate its potential mechanism of EA treatment....

Pd-catalyzed allylic alkylation of dienyl carbonates with nitromethane with high C-5 regioselectivity.

Chemical communications (Cambridge, England)

Yang XF, Li XH, Ding CH, Xu CF, Dai LX, Hou XL.
PMID: 24266021
Chem Commun (Camb). 2014 Jan 14;50(4):484-6. doi: 10.1039/c3cc46574h.

A highly regioselective palladium-catalyzed allylic alkylation of dienyl esters with nitromethane has been developed, providing selective access to the C-5 attacked products. The structures of the ligands as well as the steric effect of the substrates are important factors...

Chem Asian J. 2016 May 20;11(10):1624-30. doi: 10.1002/asia.201600304. Epub 2016 Apr 21.

Flexible memory devices have continued to attract more attention due to the increasing requirement for miniaturization, flexibility, and portability for further electronic applications. However, all reported flexible memory devices have binary memory characteristics, which cannot meet the demand of...

A quadruple cascade protocol for the one-pot synthesis of fully-substituted hexahydroisoindolinones from simple substrates.

Beilstein journal of organic chemistry

Zhang HB, Luo YC, Hu XQ, Liang YM, Xu PF.

Beilstein J Org Chem. 2016 Feb 11;12:253-9. doi: 10.3762/bjoc.12.27. eCollection 2016.

A new and efficient synthetic method to obtain fully-substituted hexahydroisoindolinones was developed by using bifunctional tertiary amine-thioureas as powerful catalysts. As far as we know, there is no efficient synthetic method developed toward fully-substituted hexahydroisoindolinones. The products were obtained...

Supramolecular Interfacial Polymerization: A Controllable Method of Fabricating Supramolecular Polymeric Materials.

A new method of supramolecular polymerization at the water-oil interface is developed. As a demonstration, an oil-soluble supramonomer containing two thiol end groups linked by two ureidopyrimidinone units and a water-soluble monomer bearing two maleimide end groups are employed....

Synthesis of N-(2-Hydroxyaryl)benzotriazoles via Metal-Free O-Arylation and N-O Bond Cleavage.

The Journal of organic chemistry

Wang ZX, Shi WM, Bi HY, Li XH, Su GF, Mo DL.
PMID: 27500856
J Org Chem. 2016 Sep 02;81(17):8014-21. doi: 10.1021/acs.joc.6b01390. Epub 2016 Aug 15.

A metal-free method for synthesis of N-(2-hydroxyaryl)benzotriazoles via O-arylation of N-hydroxybenzotriazoles with readily available diaryliodonium salts and sequential N-O bond cleavage under mild conditions has been developed. The [3,3]-rearrangement of N-O bond cleavage could take place on the N...
