Diels–Alder reactions in water*
This review illustrates how water, as an environmentally friendly solvent, can have significant additional benefits when it is used as a solvent for the Diels–Alder reaction. The mechanism by which the unique properties of water enhance the rate and selectivity are discussed. Also, possibilities for the achievement of further increases in rate and enantioselectivity of aqueous Diels–Alder react...
متن کاملAppendix 1. Diels-Alder Reactions
One of the most efficient methods (high yield, controlled stereochemistry, diverse functionality) to construct rings from smaller fragments is via cycloaddition reactions. The reverse reaction, namely splitting of a ring into smaller fragments is termed a cycloreversion reaction is also an important synthetic tool. (For example, in the present experiment it is the cracking of cyclopentadiene di...
متن کاملThe Diels-Alder cyclization of ketenimines.
A Diels-Alder reaction between cyclopentadiene and a variety of ketenimines is reported. A copper(I)-bis(phosphine complex catalyzes the cycloaddition across the C═N bond of the ketenimine in a [4 + 2] reaction to give an enamine intermediate that is hydrolyzed upon purification to generate aminoketones.
متن کاملThe Diels-Alder Reaction: an Update
In this update on the Diels-Alder reaction we would like to present an overview on how this very important reaction has progressed in the last decade, since the last spate of monographs and reviews appeared in the literature, and which deal with the reaction in the overall sense. Initially we present the Diels-Alder reaction in a generalised form, much as discovered over seventy years ago, so t...
متن کاملThe first intramolecular silene Diels-Alder reactions.
The synthesis of silaheterocycles through the first examples of an intramolecular silene Diels-Alder reaction is described.
