1,2,4-Oxadiazolidin-3,5-diones and 1,3,5-triazin-2,4,6-triones as cytosolic phospholipase A2α inhibitors
Gopalsamy, Ariamala,Yang, Hui,Ellingboe, John W.,McKew, John C.,Tam, Steve,Joseph-McCarthy, Diane,Zhang, Wen,Shen, Marina,Clark, James D.

1,2,4-Oxadiazolidin-3,5-dione and 1,3,5-triazin-2,4,6-trione scaffolds were employed as templates to incorporate the pharmacophore requirements of cytosolic phospholipase A2α substrate mimetics. Inhibitors that are active in both enzyme, and ce
One-pot copper(I)-catalyzed synthesis of 3,5-disubstituted isoxazoles
Hansen, Trond V.,Wu, Peng,Fokin, Valery V.
, p. 7761 - 7764 (2007/10/03)
3,5-Disubstituted isoxazoles are obtained in good yields by a convenient one-pot, three-step procedure utilizing a regioselective copper(I)-catalyzed cycloaddition reaction between in situ generated nitrile oxides and terminal acetylenes. Most functional

The reaction of 1-nitro-2-phenylethenes (β-nitrostyrenes) with aqueous titanium(III) chloride afforded substituted pyrroles in addition to the expected reduction products, oximes and carbonyl compounds. 2-Substituted 1-nitro-2-phenylethenes yielded divinylamine derivatives instead of pyrroles.The reaction mechanism has been rationalized by taking account of the electron transfer from titanium(III) species to the nitro olefines, followed by protonation, dimerization, cyclization, and/or hydrolysis.
TITANIUM TRICHLORIDE MEDIATED REDUCTION OF NITROSTYRENES
Sera, Akira,Fukumoto, Shoji,Yoneda, Takako,Yamada, Hiroaki
, p. 697 - 702 (2007/10/02)
Reactions of substituted nitrostyrenes with aqueous titanium trichloride afforded pyrroles, carbonyl compounds, and oximes.In some instances, divinylamines were produced as well.The reaction mechanism is rationalized taking account of electron transfer to nitroethylenes from Ti(III), followed by protonation, dimerization, cyclization, and hydrolysis.
Photochemical and Chemical Reduction of Nitroalkenes Using Viologens as an Electron Phase-Transfer Catalyst
Tomioka, Hideo,Ueda, Koichi,Ohi, Hirofumi,Izawa, Yasuji
, p. 1359 - 1362 (2007/10/02)
An amphiphilic electron acceptor, i.e., N,N'-dioctyl-4,4'-bipyridinium, was used as an electron carrier between water-oil two phase, in which nitroalkenes in organic phase were readily reduced to the corresponding oximes and/or carbonyl compounds.
