Interpretation:
The reagents necessary to achieve the given products are to be determined.
Concept introduction:
舧 Diels–Alder is a type of organic reaction in which substituted
舧 The general reaction of Diels-alder is as follows:
舧 The Diels–Alder reaction is between a conjugate diene and a reactant containing double bond (dienophile) to form a product, which is called adduct.
舧 The Diels-Alder reactions are highly stereospecific. The configuration of dienophile is retained in the product and the reaction is the syn addition.
舧 The dienes react with dienophiles in cis form rather than trans form.
舧 Endo and exo refers to the orientation of dienophile and its electron withdrawing group, when it reacts with a diene in Diels–Alder reaction.
舧 The reaction with orientation of electron–withdrawing group of dienophiles under the
舧 The reaction with orientation of electron–withdrawing group of dienophiles away from the
舧 Endo is favored in the transition state of Diels–Alder reaction because of its lower energy.
舧 If a compound is stable, it has lower energy and if a compound is unstable, it has higher energy.
