Question
Chapter 30.SE, Problem 23AP
Interpretation Introduction
Interpretation:
The manner of ring closure-conrotatory or disrotatory- for both thermal and photochemical cyclization of (2E,4Z,6Z,8Z)-2,4,6,8-decatetraene indicating the stereochemistry of the product is to be stated.
Concept introduction:
An electrocyclic reaction involves the cyclization of a conjugated acyclic system. These reactions are reversible and are highly stereospecific.
In elecrocyclic reactions involving even number of electron pairs, a thermal reaction occurs in conrotatory manner and a photochemical reaction occurs in disrotatory manner.
In elecrocyclic reactions involving odd number of electron pairs, a thermal reaction occurs in disrotatory manner and a photochemical reaction occurs in conrotatory manner.
To predict:
The manner of ring closure-conrotatory or disrotatory- for both thermal and photochemical cyclization of (2E,4Z,6Z,8Z)-2,4,6,8-decatetraene.
To state:
The stereochemistry of the product.
