Tin mediated allylation reactions of enol ethers in water.
Summary of "Tin mediated allylation reactions of enol ethers in water."
Under tin-mediated Barbier-type reaction conditions, hydration of enol ethers takes place to form aldehydes that undergo allylation reactions. By using this process, various homoallylic alcohols and 2-halohomoallylic alcohols are produced in good to excellent yields.

Cyclic AMIDES formed from aminocarboxylic acids by the elimination of water. Lactims are the enol forms of lactams.
Ethers that are linked to a benzene ring structure.
Immunologically mediated adverse reactions to medicinal substances used legally or illegally.
Halogenated Diphenyl Ethers
Compounds that contain two halogenated benzene rings linked via an OXYGEN atom. Many polybrominated diphenyl ethers are used as FLAME RETARDANTS.
Polymers of ETHYLENE OXIDE and water and their ethers. They vary in consistency from liquid to solid, depending on the molecular weight, indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are lauromagrogols, nonoxynols, octoxynols and poloxamers.
Density functional theory calculations are reported that reveal the role of aromatic interactions in the additions of aryl-substituted silyl enol ethers to a chiral oxazolinium ion. Aryl-substituted s...
Asymmetric reactions involving (E)-3-aryl-1-(pyridin-2-yl-N-oxide)prop-2-en-1-ones and cyclic enol silyl ethers show good yields and excellent enantioselectivities (up to 99.9 % ee) when catalysed b...
A highly asymmetric vinylogous addition of acyclic silyl enol ethers to siloxyvinyldiazoacetate is described. The reaction features a diastereoselective 1,4-siloxy group migration event. Products are...
An efficient and simple source of nitroso reagents and their oxidation reactions are described. The combination of a Lewis acid and a metal nitrite was applied to the oxidation of silyl enol ethers. A...
Polypropionates made EZ: The E/Z geometry of tris(trimethylsilyl)silyl super silyl enol ethers derived from propionaldehyde controls diastereoselectivity in the aldehyde crossed-aldol reaction. These...
Many individuals experience negative reactions when donating blood, including dizziness, lightheadedness, or fainting. Such reactions may discourage them from donating again. This study wi...
The study will evaluate whether the blood concentrations of eletriptan administered using two test formulations of oral disintegrating tablets are comparable to those observed with the sta...
The principal objective of this research is the evaluation of the effect of mineralized water consumption upon evolution of LDL Cholesterol and triglycerides, compared to a low mineralized...
Drinking water is largely advocated for obesity prevention and management. Recent studies have suggested that water has a thermogenic effect, this has not been examined in children. In thi...
In this study the investigators propose to assess the hemodynamic response to the ingestion of 16 fl oz of water. The investigators will test the hypothesis that water ingestion will incr...
