pericyclic reaction

This is the single known example of an enzyme catalyzing a pericyclic reaction.

One important class of these is pericyclic reactions.

Alkynes are also used a lot in pericyclic reactions.

Torquoselectivity is different from the normal diastereoselectivity of pericyclic reactions.

Like all pericyclic reactions, they must obey the Woodward-Hoffmann rules.

In pericyclic reactions, the orbital interactions are important.

By the above rules, for a 4n electron pericyclic reaction of 2 components, there must be one antarafacial component.

These elementary steps can be classified in a few major classes: addition, elimination, substitution, and pericyclic reactions.

A sigmatropic reaction in organic chemistry is a pericyclic reaction.

Some pericyclic reactions go with heat, some go only with light.

Cheletropic reactions are a type of pericyclic reaction.

Using correlation diagrams one can derive selection rules for the following generalized classes of pericyclic reactions.

In pericyclic reactions, explanation by orbital interactions give a better picture than simple discrete electron transfers.

A pericyclic reaction is a type of reaction with multiple carbon-carbon bond making and breaking.

The transition states for these reactions typically involves the electrons of the molecules moving in continuous rings, making it a pericyclic reaction.

This method correctly predicts the WH rules for the major classes of pericyclic reactions.

Any pericyclic reaction can be treated of as a concerted intramolecular cycloaddition reaction.

Thus a 4n pericyclic reaction is thermally allowed if the total number of antarafacial components is odd.

Three key rearrangement reactions are 1,2-rearrangements, pericyclic reactions and olefin metathesis.

Houk discovered that there are normal bond lengths for transition structures of hydrocarbon pericyclic reactions.

This transformation is a group transfer pericyclic reaction, and therefore, usually requires highly activated substrates and/or high temperatures.

In the Dewer-Zimmerman analysis, one is concerned with the topology of the transition state in the pericyclic reaction.

Cycloadditions often have metal-catalyzed and stepwise radical analogs, however these are not strictly speaking pericyclic reactions.

Pericyclic reactions are concerted reactions.

This prediction agrees with experiment as the Diels-Alder reaction is a rather facile pericyclic reaction.
