Authors: Zhang Yuan , Han Mengting , Ye Qiong , Xiong Rengen 
Published: September 2010

AbstractThe molten reaction of 2‐naphthol, 2‐hydroxybenzaldehyde and tetrahydropyrrole at about 120°C yields 1‐[(2‐hydroxyphenyl)(pyrrolidin‐1‐yl)‐methyl]naphthalen‐2‐ol, whose co‐crystal (1) with 2‐naphthol was characterized by X‐ray single crystal diffraction, XRPD and IR. Compound 1 crystallizes in a noncentrosymmetric space group (Fdd2) with unit cell dimensions of a=2.9395(9) nm, b=3.468(3) nm, c=0.8013(8) nm, V=8.170(13) nm3, α=β=γ=90.0° and Z=8 [at 293(2) K]. The piezoelectric measurement result shows compound 1 is piezoelectrically active material with d33 value of ca. 6.2 pC/N. Temperature‐ and frequency‐dependent dielectric constant of compound 1 were measured and showed no distinct dielectric anomaly, which suggest no phase transition within the measured temperature range (100–410 K).
Theoretical Investigation on the Mechanism and Design of Catalysts for Nitrolysis of Hexamine
Authors: Shi Liangwei , Zhao Gang , Zhang Yazhu , Zheng Changwu , Qin Guangming , Lü Jian 
Published: September 2010

AbstractThe mechanism of nitrolysis of hexamine (HA) by DFT method has been explored to understand the classical organic reaction and assist the design of new catalyst. The potential energy surface of NO+2 was firstly investigated. A reasonable configuration evolution of NO+2 during the process of its reaction with HA was figured out. The role of H+ and NH+4 for the nitrolysis of HA was analyzed and discussed. The route of nitrolysis reaction from HA to 1‐acetoxylmethene‐3‐nitro‐tetrazabicyclo[3,3,1]nonane intermediate is similar to that of acetylation of HA. The relative free energy calculation proves the priority of nitrolysis relative to acetylation. Two types of Lewis salts, M(OSO2CF3)3 and M[N(SO2CF3)2]3 (M: Yb, Sm, Y, and Eu), are designed on the basis of discussed mechanism. The calculation for the key bond order in IM2[CH2R] model intermediates gives an indicator as the preferable catalyst. The experimental results support the theoretical conclusion.
Construction and Biofunction of 3‐Dimensional Self‐assembly Collagen Nanostructure on PLLA Substrate
Authors: Xu Shouhong , Liu Aiping , Lin Xiaoxiao , Liu Honglai , Yonese Masakastu 
Published: September 2010

AbstractA 3‐dimensional and multi‐layered network nanostructure of collagen assembled on the poly(L‐lactic) acid (PLLA) substrate was reported. Collagen adsorption layers were prepared by dipping PLLA substrates into collagen solutions with various pH. The influences of adsorption interval, pH of collagen solutions and properties of PLLA substrate on the adsorption behavior of collagen were investigated by using atomic force microscopy and ellipsometry measurements. It was found that the multiple association degrees of collagen molecules in solution at a certain pH value seemed to play an important role in the adsorption process. The distinct adsorption behavior determined a specific 3‐dimensional structure formed at the interface. Furthermore, calcium carbonate (CaCO3) can be biomimetically crystallized by the inducement of biomineralization on these collagen layers.
The [2+2]‐Cycloaddition Reaction of Bisallenes: A Dramatic Substituent Effect
Authors: Lu Ping , Ma Shengming 
Published: September 2010

AbstractThe bisallenes 1 possessing a phenylsulfonyl or n‐butyl substituent at the internal position of allene moieties could be smoothly transformed to the bicyclo[5.2.0] or bicyclo[6.2.0] derivatives 2 in moderate to excellent yields with good regioselectivity upon refluxing in toluene. This [2+2]‐cycloaddition reaction shows an interesting substituent effect as unveiled by comparing with the results of unsubstituted substrates. However, further attention should be paid to the control of the regioselectivity of the [2+2]‐cycloaddition involving different CC bonds.

Authors: Hao Chao , Zhang Yihua , Jiang Yongwen , Ma Dawei 
Published: September 2010

AbstractThe ortho‐substituent effect directed by the CF3CONH group exists in CuBr/N,N‐dimethylglycine‐catalyzed diaryl ether formation from o‐chlorotrifluoroacetanilides and phenols, leading to this coupling reaction proceeding at 80°C to afford a wide range of diaryl ethers. The halogen‐exchange also plays an important role in this transformation because adding potassium iodide is essential for complete conversion.

Authors: Zhang Jianxin , Yang Dazhi , Xiao Zuo , Gan Liangbing 
Published: September 2010

AbstractThe fullerene‐mixed peroxide C60(O)(OOt‐Bu)6 was found to react with FeCl3 to form open‐cage compounds C60(O)4(OOt‐Bu)4 2 and C60(O)2(OH)(OOt‐Bu)5 3. Addition of hydroxyl amine to 3 closes the opening, yielding compound 5 with a hemiacetal and hemiaminal moiety. Oxidation of 5 with diacetoxyliodobenzene eliminates the hydroxylamine addend and reforms the open‐cage compound 3.
Synthesis of Bisazacalix[n]pyridines and Their Complexation with C60 and C70
Authors: Zhang Enxuan , Wang Dexian , Huang Zhitang , Wang Meixiang 
Published: September 2010

AbstractDisulfane‐linked bisazacalix[n]pyridines (n=4, 7) were synthesized for the first time using a macrocyclic fragment coupling approach followed by post‐macrocyclization photoreaction with ethanethioic acid and hydrolysis under basic conditions. The bis‐macrocyclic compounds acted as strong receptors to form 1:1 complex with C60 and C70, giving a binding constant (Ka(1:1)) up to 107000 L·mol−1. The cooperation of two mono‐macrocyclic improved binding affinity to fullerenes.
Enantioselective Synthesis of the Diazatricyclic Core of Alkaloid TAN1251C via an Iodoaminocyclization Reaction
Authors: Zhang Hongkui , Lin Zhijie , Huang Huang , Huo Haohua , Huang Yanju , Ye Jianliang , Huang Peiqiang 
Published: September 2010

AbstractA concise enantioselective synthesis of the diazatricyclic core of alkaloid TAN1251C is reported. The method featured a stereoselective formation of the iodide intermediate 16b (in 2:1 ratio) from homoallylic amine 11b by iodine‐promoted iodoaminocyclization, a previously claimed to be unsuccessful reaction. The intermediate 16b was converted to the tricyclic core of TAN1251C 28 in five steps. During this study, two unexpected products 22 and 25 were obtained, and compound 23, derived from 11a was shown to be unsuitable for the oxidative formation of the enamide of TAN1251C.

Charge‐Transfer Effect on Chiral Phosphoric Acid Catalyzed Asymmetric Baeyer‐Villiger Oxidation of 3‐Substituted Cyclobutanones Using 30% Aqueous H2O2 as the Oxidant
Authors: Xu Senmiao , Wang Zheng , Zhang Xumu , Ding Kuiling 
Published: September 2010

AbstractThe intermolecular charge‐transfer effect has been employed for the first time as a modulating approach to affect the enantioselectivity in asymmetric catalysis by taking the chiral phosphoric acid catalyzed asymmetric Baeyer‐Villiger oxidation of 3‐aryl cyclobutanones as the reaction prototype. It was found that the electron acceptor additives were able to effectively tune the enantioselectivity via donor‐acceptor interaction with the catalyst and up to 9% enhancement of ee value was observed in a favorable case.
A 2,2′‐Bipyridyl‐Bridged Tetrathiafulvalene‐quinone Dyad: Intramolecular Electron‐Transfer Promoted by Metal Ions
Authors: Huang Guangxi , Zhang Deqing , Zhang Guanxin , Zhu Daoben 
Published: September 2010

AbstractA 2,2′‐bipyridyl‐bridged tetrathiafulvalene (TTF)‐quinone dyad (1) was synthesized and characterized. Both absorption and ESR spectroscopic studies clearly indicate that electron transfer occurs from TTF to the quinone unit for dyad 1 in the presence of metal ions. The results manifest that the coordination of dyad 1 with metal ions plays a key role in facilitating the intramolecular electron transfer.

Moreover, product 2, the solution‐phase rearrangement product of compound 1, was synthesized and its gas‐phase chemistries were also studied to support the propos gas‐phase rearrangement reactions of compound 1.
Conversion of Glucose in CPL‐LiCl to 5‐Hydroxymethylfurfural
Authors: Chen Tianming , Lin Lu 
Published: September 2010

Abstract5‐Hydroxymethylfurfural (HMF), an important versatile sugar derivative, is also considered a key intermediate between petroleum‐based industrial organic chemistry and bio‐based carbohydrate chemistry. Here, we report that caprolactam (CPL) containing lithium chloride (LiCl) is a privileged solvent that enables the synthesis of the renewable platform chemical 5‐hydroxymethylfurfural (HMF) from purified glucose. Metal halides in CPL‐LiCl are catalysts, among which CrCl3, CrCl2, SnCl4 and SnCl2 are found to be uniquely effective, leading to the conversion of glucose to HMF with yields of 55% –67%. The simplicity of this chemical transformation of glucose contrasts markedly with the complexity of extant processes and provides a new paradigm for the use of biomass as a raw material for a renewable energy and chemical industries.
