Concept explainers
Interpretation:
The structures of the two Diels-Alder adducts formed when isoprene (2-methyl-1, 3-butadiene) reacts with ethyl propenoate are to be given and why a mixture of products is formed is to be explained.
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. These reactions occur rapidly with dienophiles having electron withdrawing substituent groups in conjugation with the double bond and if the diene adapts a s-cis conformation during the reaction.
To give:
The structures of the two Diels-Alder adducts formed when isoprene (2-methyl-1, 3-butadiene) reacts with ethyl propenoate and to explain why a mixture of products is formed.

- Oximene and myrcene, two hydrocarbons isolated from alfalfa that have the molecular formula C10H16, both yield 2,6- dimethyloctane when treated with H2 and a Pd catalyst. Ozonolysis of oximene forms (CH3)2C = O, CH2 = O, CH2(CHO)2, and CH3COCHO. Ozonolysis of myrcene yields (CH3)2C = O, CH2 = O, (two equiv), and HCOCH2CH2COCHO. Identify the structures of oximene and myrcene.arrow_forwardAs an example of a ver rare occurence, the following hydrocarbon reacts with two equivalents of butylithium to form a dianion of the formula [C8H6]2- .
