Unformatted text preview: + HO — H 2 We will later learn better ways of making alcohols, such as making them from either aldehydes or esters. 4. O O CH 3 O + O O H CH 3 O Several characteristics of the Diels-Alder reaction are illustrated by this. (1) Only the methyl-substituted double bond reacts. The methoxy-substituted one is too electron-rich. (2) The cis ring fusion retains the stereochemistry of the double bond in the dienophile. (3) Further cycloaddition of diene to the product does not occur because the double bonds in the product are not sufficiently electron-deficient to react at an appreciable rate....
