Question
Predict the products of the following Diels-Alder reaction:
(b)
Step-by-Step Solution
VerifiedDiels-Alder reaction was discovered by the German chemists Otto Diels and Kurt-Alder in 1928. Diels-Alder reaction is an important cycloaddition reaction which is stereospecific. It includes a substituted alkene in the form of a dienophile and a conjugated diene. It proceeds via concerted mechanism. Diels alder reaction can be used to generate 6 membered rings since there is a simultaneous construction of two new Carbon-carbon bonds. Stereochemistry of the dienophile is retained.
Diene is an organic compound which comprises of two conjugated pi bonds (4 pi bonds) while dienophile is a diene loving compound containing 2 pi electrons.
The Diene is
The dienophile is,
The reaction is stereospecific (single stereoisomer is obtained) .Endo product is formed as a result of Diels-Alder reaction. A substituent on one bridge is endo when it is cis to the larger of the other two bridges.
