Question
Chapter 28, Problem 28.52AP
Interpretation Introduction
Interpretation:
An interesting heterocyclic compound C was prepared and trapped by the sequence of reactions given in Fig. P28.52.The structure of all missing compounds is to be explained.
Concept introduction:
Electrocyclic reactions are a pericyclic reaction which occur intramolecularly. These reactions will result in the formation of ring compounds under the influence of heat or light. Notably, in this process one new sigma bond is formed and one old π-bond is consumed. Intriguingly, the reverse ring opening electrocyclic reaction can also be possible to occur under the same reaction mechanism but in reverse manner.
