The hepatotoxic action of allyl formate on rat liver has been investigated. Biochemical changes can be detected in the liver cell many hours before the histological changes and it would appear that the toxin has a direct action on the liver parenchymal cell. The results suggest that allyl formate is not the toxic agent but that it is converted via allyl alcohol into acrolein. This reaction requ...

substituted naphthofurans and naphthopyrans were constructed at high temperature from allyl or propargyl naphthyl ethers via claisen rearrangement in moderate to good yields. also, substituted (trimethylsilyl)-naphthofurans were synthesized from the corresponding naphtofurans.

Thiosulfonates are characterized by a wide spectrum of biological activity and have effective antimicrobial, antithrombotic, antitumor antiparasitic effects. However, the use synthetic sulfur-containing compounds for therapeutic preventive purposes requires study their effect on protective mechanisms maintaining homeostasis, antioxidant status body in particular. The aim was to estimate lipid p...

The insertion of an olefinic C=C bond into a metal-carbon bond is of potential interest as a preparativeroute to new products and as results of C-C coupling reactions to organic compounds. The allyl compoundsof Mg, react with an olefin by inversion of the allyl group via a six center transition state. These precyclicreactions may be one of the most important classes of organic reactions. The re...

Photochemically driven reactions involving unsaturated radicals produce a thick global layer of organic haze on Titan, Saturn's largest moon. The allyl radical self-reaction is an example for this type of chemistry and was examined at room temperature from an experimental and kinetic modelling perspective. The experiments were performed in a static reactor with a volume of 5 L under wall free c...

A key limitation in modern biology is the ability to rapidly identify genes underlying newly identified complex phenotypes. Genome wide association studies (GWAS) have become an increasingly important approach for dissecting natural variation by associating phenotypes with genotypes at a genome wide level. Recent work is showing that the Arabidopsis thaliana defense metabolite, allyl glucosinol...

Cruciferous vegetables, such as Brassica, which contain substantial quantities of glucosinolates, have been suggested to possess anticarcinogenic activity. Cutting and chewing of cruciferous vegetables releases the thioglucosidase enzyme myrosinase, which degrades glucosinolates to isothiocyanates and other minor metabolites. Cooking of cruciferous vegetables inactivates the myrosinase enzyme, ...

The selective oxidation of propylene to acrolein was investigated over a well-defined supported V2O5/Nb2O5 catalyst, containing a surface vanadia monolayer, with combined operando Raman/IR/MS, temperature programmed surface reaction (TPSR) spectroscopy and isotopically labeled reactants (O2 and C3D6). The dissociative chemisorption of propylene on the catalyst forms the surface allyl (H2CdCHCH2...

The ball milling of beryllium chloride with two equivalents of the potassium salt of bis(1,3-trimethylsilyl)allyl anion, K[A′] (A′ = [1,3-(SiMe3)2C3H3]), produces the tris(allyl)beryllate K[BeA’3] (1) rather than the expected neutral BeA’2. The same product is obtained from reaction in hexanes; in contrast, although a similar reaction conducted in Et2O was previously shown to produce the solvat...
