Question
Chapter 14.SE, Problem 24MP
Interpretation Introduction
Interpretation:
The structure of the Diels-Alder adduct formed in the reaction between Danishfsky’s diene with acrolein a mechanism that accounts for the formation of final products is to be given.
Concept introduction:
In Diels-Alder reaction, a dienophile reacts with a diene to yield a cyclic adduct. The reaction takes place through 1,4 addition of the dienophile into the diene through a cyclic transition state.
To give:
The structure of the Diels-Alder adduct formed in the reaction between Danishfsky’s diene and acrolein with a mechanism that accounts for the formation of final products.
