Synthesis of Tris-hydroxymethyl-Based Nitrone Derivatives with Highly Reactive Nitronyl Carbon

A novel series of a-phenyl-N-tert-butyl nitrone derivatives, bearing a hydrophobic chain on the aromatic ring and three hydroxyl functions on the tert-butyl group, was synthesized through a short and convenient synthetic route based on a one-pot reduction/condensation of tris(hydroxymethyl)nitromethane with a benzaldehyde derivative. Because of the presence of hydroxyl functions on the tert-butyl group, an intramolecular Forrester-Hepburn reaction leading to the formation of an oxazolidine-N-oxyl compound was observed by electron paramagnetic resonance (EPR). The mechanism of cyclization was further studied by computational methods showing that intramolecular hydrogen bonding and high positive charge on the nitronyl carbon could facilitate the nucleophilic addition of a hydroxyl group onto the nitronyl carbon. At high nitrone concentrations, a second paramagnetic species, very likely formed by intermolecular nucleophilic addition of two nitrone molecules, was also observed but to a lesser extent. In addition, theoretical data confirmed that the intramolecular reaction is much more favored than the intermolecular one. These nitrones were also found to efficiently trap carbon-centered radicals, but complex spectra were observed due to the presence of oxazolidine-N-oxyl derivatives.

The expression of detoxification genes in two maize cultivars by interaction of isoxadifen-ethyl and nicosulfuron

Herbicide safeners protect crop plants from herbicide phytotoxicity, but an understanding of their molecular mechanisms is still lacking. We investigated the effects of the safener isoxadifen-ethyl and/or nicosulfuron on the expression of 10 genes, 8 glutathione transferases (GSTs), 1 glutathione transporter and 1 multidrug resistance protein gene in two maize cultivars. Nicosulfuron and isoxadifen-ethyl induce different detoxification enzyme genes. The expression analyses of the 10 genes revealed that most were expressed much higher in ‘Zhengdan958’ than those in ‘Zhenghuangnuo No.2’, both in control and in isoxadifen-ethyl- and/or nicosulfuron-treated plants. The expression levels of ZmGSTIV, ZmGST6, ZmGST31 and ZmMRP1 in two maize cultivars were up-regulated by isoxadifen-ethyl only, or in combination with nicosulfuron, whereas nicosulfuron down-regulated the expression of eight genes. Thus, ZmGST1V, ZmGST6, ZmGST31 and ZmMRP1 could be considered safener-responsive and may be the core genes responsible for isoxadifen-ethyl increasing the tolerance of maize to nicosulfuron.

Regio-selective reduction of the C-C double bonds in alpha,beta-unsaturated acyl 4-substituted oxazolidin-2-ones and oxazolidine-2-thiones

Selective saturation of the conjugated C-C double bonds in the title compounds was examined in a systematic way for the first time. Many established protocols effective for similar reduction of alpha,beta-unsaturated ketones and esters in the literature were found to be inapplicable in the present context. The most satisfactory results were finally obtained using the DIBAL-H/MeLi/Cul/HMPA/THF conditions. (C) 2011 Elsevier Ltd. All rights reserved.

Electrooxidative Cyclization of Hydroxyamino Compounds Possessing a Benzyl Group

Several novel 2-aryl-1,3-oxazinane and 2-aryl-1,3-oxazolidine derivatives were synthesized from N-benzyl-2-piperidineethanols and N-benzyl-2-piperidinemethanols, respectively, by using electrooxidative methods in methanol. For these reactions, the yields of the corresponding cyclized compounds were significantly increased by using catalytic amounts of iodide ions. In contrast, 3-dialkylamino-1-phenylpropanols afforded the expected cyclic 6-phenyl-1,3-oxazinane derivatives using only a small excess of base.
