The enantioselective domino reaction between CO2 (1 atm), amines and linear allyl chlorides in the presence of an iridium complex, DABCO and toluene at 15 °C was realized, which gave branched allyl carbamates in acceptable to high yields with up to excellent regioselectivity (99/1) and 94% ee. This is the first example of the synthesis of chiral allyl carbamates through catalytic domino reactio...

Allyl sulfides are bioactive phytochemicals found in garlic, onion, and other members of the genus Allium. Here we showed that diallyl disulfide and diallyl trisulfide can transfer allyl side chains to low molecular weight thiols. Diallyl monosulfide is inert with respect to this allyl transfer reaction. On the other hand, diallyl sulfone, a known metabolite of diallyl monosulfide, alkylates bo...

A dual vicinal functionalisation cascade involving the union of heterocycles and allyl sulfoxides is described. In particular, the approach provides efficient one-step access to biologically relevant and synthetically important C3 thio, C2 carbo substituted indoles. The reaction operates under mild, metal free conditions and without directing groups, via an interrupted Pummerer coupling of acti...

the conformation of alinidine a new and specific bradycardic agent was studied using mndo method. it has been found that the rotation of both phenyl and imidazoline ring of this compound is restricted. of two possible isomers of irnidazoline ring, the one with nh in the cis position to allyl side chain is slightly more stable. on the other hand, the allyl group can rotate freely and at least si...

In rats 2-allyl-2-isopropylacetamide causes a porphyria with many similarities to acute intermittent porphyria in man (Goldberg & Rimington, 1955; Tschudy & Bonkowsky, 1972). The finding that patients suffering from acute intermittent porphyria may have abnormal steroid-excretion patterns (Goldberg et al., 1969; Kappas et al., 1971) prompted an investigation of the effects of 2-allyl-2-isopropy...

A new method for the synthesis of allyl aromatic compounds not involving any metal-containing reagent or catalyst has been developed. Arylamines substituted with a large number of different substituents were converted via diazotizative deamination with tert-butyl nitrite in allyl bromide and acetonitrile to the corresponding allyl aromatic compounds. The allylation reaction was found to be suit...

Abstract Ynamides bearing a tethered allyl sulfoxide undergo gold-catalysed cycloisomerisation to afford tetrahydrothiophene-2-carboxamides and their benzo-fused analogues. The reactions are initiated by formal 7-endo-dig cyclisation accommodate range of different substituents. use N-allyl ynamides provided route into novel spirocyclic ε-lactam structures.

The pungent natural compound allyl isothiocyanate isolated from the seeds of Cruciferous (Brassica) plants such as mustard is reported to exhibit numerous beneficial health-promoting antimicrobial, antifungal, anticarcinogenic, cardioprotective, and neuroprotective properties. Because it is also reported to damage DNA and is toxic to aquatic organisms, the objective of the present study was to ...

Fish embryos are widely used as an alternative model to study toxicity in vertebrates. Due to their complexity, embryos are believed to more resemble an adult organism than in vitro cellular models. However, concerns have been raised with respect to the embryo's metabolic capacity. We recently identified allyl alcohol, an industrial chemical, to be several orders of magnitude less toxic to zebr...
