- In situ synthesis of 2-allyloxy-1-methylpyridinium triflate for the allylation of carboxylic acids
-
2-Allyloxypyridinium triflate is formed in situ by treating a mixture of 2-allyloxypyridine, a carboxylic acid, and toluene with methyl triflate. Subsequent warming of the reaction mixture in the presence of potassium carbonate leads to efficient formation of allyl esters in good to excellent yields.

- Alkylation of the 2-hydroxypyridine anion in ionic liquid media
-
The alkylation reaction of the ambident 2-hydroxypyridine anion was examined in ionic liquid media. Ionic liquids increase the alkylation reaction rate in comparison with molecular liquids, as well as the level of impact on the reaction rates of the count

- Indium-mediated deoxygenation of amine-N-oxides in aqueous media
-
Several aromatic and aliphatic amine-N-oxides were deoxygenated to the corresponding amines in good to quantitative yield using indium metal in neutral aqueous media. Other functional groups such as alkenes, halides, esters, ethers, nitriles, amides and sulfones are unaffected under the present reaction conditions. (C) 2000 Elsevier Science Ltd.

- Auxiliary accelerated reactions: Towards the use of catalytic chiral auxiliaries
-
In competition experiments, the acceleration of reactivity of alkenes tethered to pyridyl groups compared with the corresponding alkenes tethered to phenyl groups in the presence of transition metals was demonstrated for two reaction types: Diels-Alder cycloaddition of enoate esters and catalytic hydrogenation of allylic and homoallylic ethers. The rate accelerations observed are of crucial importance in the development of a new concept for asymmetric catalysis: chiral auxiliaries which can function in a catalytic manner.
