Isolation of microbe for asymmetric reduction of prochiral aromatic ketone and its reaction characters

YANG Zhonghua, WANG Yu, WANG Guanghui, ZENG Rong, YAO Shanjing

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 4,   Pages 416-420 doi: 10.1007/s11705-007-0076-7

Abstract: The favorable microbes for the asymmetric reduction of prochiral aromatic ketones was isolated from soil using acetophenone as the sole carbon source, when the asymmetric reduction of acetophenone (ACP) to chiral ?-phenethyl alcohol (PEA) was chosen as the model reaction. Two microbe strains with excellent catalytic activity were obtained. They were and identified by bacteria identification. The product of the asymmetric reduction of ACP catalyzed by was mainly R-PEA and that by was mainly S-PEA. The yield and enantiomeric excesses (e.e.) could respectively reach 75% and 90% for , and 80% and 70% for , much higher than those catalyzed by baker s yeast.

Joint effects of Penta-BDE and heavy metals on

Baohua TANG, Lingyan ZHU, Qixing ZHOU

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 1,   Pages 99-110 doi: 10.1007/s11783-010-0260-8

Abstract: The joint toxicity of Penta-BDE (Pe-BDE) and heavy metals including cadmium and copper on ( ) was evaluated on the basis of determining the 48 h survival, antioxidative enzyme responses, and lipid peroxidation. The response was classified as additive, greater than additive, or less than additive by comparing the measured “toxic units, TU” with one. Based on the survival of , less-than-additive interactions were found in most of mixtures treatments. This may be attributed to the different toxicity mechanism between Pe-BDE and metals. Cu and Cd played a greater role in toxicity than what Pe-BDE did. As for the superoxide dismutase (SOD) and catalase (CAT) activity, most response was less than additive. For the glutathione -transferases (GST) activity, most of the greater-than-additive responses were found in the Cu plus Pe-BDE treatments, but the additive responses occurred in Cd plus Pe-BDE treatments and binary metal treatments. For lipid peroxide levels, which were measured as malondialdehyde (MDA) levels, less-than-additive response occurred in the 50% Cd plus 50% Cu and ternary mixture treatments. Results suggested that Pe-BDE, Cd, and Cu could induce different patterns of antioxidant enzyme responses, such as antioxidant/prooxidant responses, depending on their capability to produce reactive oxygen species and antioxidant enzymes to detoxify them.

One-pot three-component Mannich reaction catalyzed by sucrose char sulfonic acid

Qiong XU, Zhigao YANG, Dulin YIN, Jihui WANG

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 2,   Pages 201-205 doi: 10.1007/s11705-009-0052-5

Abstract: Sucrose char sulfonic acid efficiently catalyzed the one-pot three-component Mannich reaction of ketones, aromatic aldehydes and amines in ethanol to afford the corresponding -amino carbonyl compounds in good to excellent yields. A series of heteroaromatic -amino carbonyl compounds can be obtained when using 2-acetylpyrazine as substrate. This reaction can be performed under mild reaction conditions with clean reaction profiles and a simple workup procedure.
