Sphingobium yanoikuyae TJ is a halotolerant di-n-butyl-phthalate-degrading bacterium, isolated from the Haihe estuary in Bohai Bay, Tianjin, China. Here, we report the 5.1-Mb draft genome sequence of this strain, which will provide insights into the diversity of Sphingobium spp. and the mechanism of phthalate ester degradation in the estuary.

The copper-catalyzed and iodosylbenzene-mediated aziridination of (S)-N-(9phenylfluorenyl)allylglycine tert-butyl ester 10 led to the isolation of the corresponding aziridine 13 in 28% yield (65% based on consumed starting material). The (2S,4S) isomer was preferentially formed with a diastereomeric excess of 36%.

In this experiment, the chemical composition of the essential oils obtained from Ferula assa-foetida oleo-gum resin collected from two different sites of Yazd province (Tabas and Yazd) in the center of Iran, were identified. The gas chromatography mass-spectroscopy (GC/MS) data showed that the qualitative composition of the components appeare...

Chiral BOX-Cu(OTf)2 catalyzed enantioselective aminolactonization of the tert-butyl ester of alkenoic acids has been developed via in situ aziridination using PhINNs as the nitrene source. It provides exclusively trans-γ- and δ-amino lactones including an additional all-carbon quaternary stereo-centre with up to 98% ee in good to excellent yields.

An efficient method for the synthesis of the natural product (+)-(R)-butyl ester of rosmarinic acid (+)-(R)-1 and its enantiomer ( - )-(S)-1 has been developed by chemical resolution of its phenyl lactic acid precursors 4 with ( - )-menthol. Their antioxidative and anti-tumor activities were evaluated.

An efficient, catalytic, diastereo- and enantioselective conjugate addition of N-(diphenylmethylene)glycine tert-butyl ester to β-aryl substituted enones was realized in the presence of 1 mol% of newly desired dinuclear N-spiro-ammonium salts, affording functionalized α-amino acid derivatives in 57-98% yields with high diastereoselectivity (up to 99:1 dr) and enantioselectivity (up to 96.5:3.5 ...

A series of feeding experiments were undertaken with weaner cattle to assess the effects on liveweight performance of supplementing a basal diet of molasses, urea and roughage with various protein and energy supplements. The supplements included extruded soyabeans, a mixture of extruded soyabean and crushed maize grain, or soyabean and crushed maize extruded together. These experiments indicate...

Received Sep 2, 2016 Revised Aug 2, 2017 Accepted Aug 30, 2017 For decades, petroleum-based mineral oils are the insulating media conventionally used in the industry, particularly for high voltage (HV) applications. However, due to the disadvantages of mineral oils, there is growing interest in replacing these oils with environmentally friendly alternatives in order to fulfill the demanding req...

Prostate cancer (PCa) has been linked to fat intake, but the effects of both different dietary fat levels and types remain inconsistent and incompletely characterised. The effects on PCa in the transgenic adenocarcinoma of the mouse prostate (TRAMP) cancer model of an elevated fat (20 % of energy as fat) diet containing 155 g of whole walnuts were compared to those of an elevated fat (20 % of e...

This work presents the effect of nanoparticles (Al2O3 and TiO2) on methyl ester synthesized from palm kernel oil for oil-filled power equipment. It investigates loss tangent, AC conductivity, breakdown strength ester-based nanofluid. The surface was functionalized with oleic acid before dispersing it into to modify stability mixture. Scanning electron microscopy coupled dispersive X-ray done tw...
