BF3.OEt2-Mediated Benzylation of Arenes and Heteroarenes with Benzyl Ether Derivatives  [PDF]
Ling Dang, Qiang Li, Tongmei Ma, Sheng Sheng, Wei Zeng
International Journal of Organic Chemistry (IJOC) , 2011, DOI: 10.4236/ijoc.2011.14026
Abstract: An efficient BF3.OEt2-promoted benzylation of arenes and heteroarenes with various benzyl ether derivatives has been developed. This method provided alternative access to valuable diarylmethane in good yields under mild conditions via an easy work-up procedure.
Neurobiology of Acupuncture: Toward CAM

Evidence-Based Complementary and Alternative Medicine , 2004, DOI: 10.1093/ecam/neh017
Abstract: It has long been accepted that acupuncture, puncturing and scraping needles at certain points on the body, can have analgesic and anesthetic effects, as well as therapeutic effects in the treatment of various diseases. This therapy, including acupuncture anesthesia, has drawn the attention of many investigators and become a research subject of international interest around the world. Numerous studies have demonstrated that the nervous system, neurotransmitters, endogenous substances and Jingluo (meridians) may respond to needling stimulation and electrical acupuncture. An abundance of information has now accumulated concerning the neurobiological mechanisms of acupuncture, in relation to both neural pathways and neurotransmitters/hormonal factors that mediate autonomic regulation, pain relief and other therapeutics. Early studies demonstrated that the analgesic effects of electroacupuncture (EA) are mediated by opioid peptides in the periaqueductal gray. Recent evidence shows that nitric oxide plays an important role in mediating the cardiovascular responses to EA stimulation through the gracile nucleus-thalamic pathway. Other substances, including serotonin, catecholamines, inorganic chemicals and amino acids such as glutamate and α-aminobutyric acid (GABA), are proposed to mediate certain cardiovascular and analgesic effects of acupuncture, but at present their role is poorly understood. The increased interest in acupuncture health care has led to an ever-growing number of investigators pursuing research in the processes of the sense of needling touch, transduction of needling stimulation signals, stimulation parameters and placebos. In this Review, the evidence and understanding of the neurobiological processes of acupuncture research have been summarized with an emphasis on recent developments of nitric oxide mediating acupuncture signals through the dorsal medulla-thalamic pathways.
1-Methylsulfonyl-4-nitrobenzene
Dong-Sheng Ma
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808035861
Abstract: In the title compound, C7H7NO4S, the nitro group is twisted by 10.2 (5) ° out of the plane of the benzene ring. Inversion-related molecules are linked by non-classical C—H...O hydrogen bonds into dimers featuring an R22(10) motif.
Poly[[triaqua[μ4-N-(4-carboxylatophenyl)iminodiacetato]sodium(I)zinc(II)] dihydrate]
Dong-Sheng Ma
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808036441
Abstract: In the title coordination polymer, {[NaZn(C11H8NO6)(H2O)3]·2H2O}n, the Zn atom is coordinated in a distorted tetrahedral environment by three carboxylate O atoms from two (4-carboxylatophenylimino)diacetate ligands and one water molecule; the Na atom is in an distorted octahedral coordination environment formed by four carboxylate O atoms from three (4-carboxylatophenylimino)diacetate ligands and two water molecules. The Zn atoms and Na atoms are linked by (4-carboxylatophenylimino)diacetate ligands into a three-dimensional framework; the uncoordinated water molecules fill the voids of the skeleton and stabilize it by O—H...O hydrogen bonds.
