Concept explainers
Interpretation:
The structures of the product when 1,3-butadiene reacts with the given dienophiles are to be given.
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 the product and the product is called adduct.
舧 Diels–Alder reactions are highly stereospecific. The configuration of dienophile is retained in the product and the reaction is syn addition.
舧 The dienes react with dienophiles in cis forms rather than trans forms.
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.
