Question: What type of pericyclic reaction is illustrated in each reaction?

Short Answer

Expert verified

Answer

Step by step solution

01

Electrocyclic reaction

The pericyclic reactions that involve the conversion of a sigma bond to a pi bond or vice-versa are known as electrocyclic reactions.

02

Sigmatropic rearrangement

The reactions that involve the migration of a sigma bond followed by the delocalization of a pi bond are known as sigmatropic rearrangement reactions.

03

Given reactions

The pericyclic reactions involved in the given reactions are as follows.

Electrocyclic reaction

The given reaction involves the electrocyclic ring-opening.

Sigmatropic rearrangement

The given reaction involves a [1,2] hydrogen shift and, therefore, is a sigmatropic reaction.

Electrocyclic ring closure

The given reaction is an electrocyclic ring-closure reaction.

Question:Draw the product (including stereochemistry) formed from each pair ofreactants in a thermal [4 + 2] cycloaddition reaction.

Question: Show how the following starting material is converted to the given product by a series of two pericyclic reactions. Account for the observed stereochemistry.

Question: What cyclic product is formed when each decatetraene undergoes thermal electrocyclic ring closure?

Question:(a) Draw the product of the following [4 + 2] cycloaddition, which was carried out in the early stages of the synthesis of the alkaloid reserpine (Problem 22.83). Indicate the stereochemistry at any newly formed stereogenic centers. (b) Draw the porbitals of the alkene and the terminal carbons of the conjugated diene, and show how the orientation of the reactants and orbital overlap lead to the observed stereochemistry.

Question: What product is formed when each compound undergoes thermal electrocyclic ring-opening or ring closure? Label each process as conrotatory or disrotatory and clearly indicate the stereochemistry around tetrahedral stereogenic centers and double bonds.
