The task is to identify the major products formed in two specific reactions. The reactants include a 1,3-dicarbonyl compound and (E)-3-phenylprop-2-enoate for the first reaction, and (E)-3-methylbut-2-enoate for the second. The major products are identified as D = 3-phenyl-3-hydroxybutanoate and E = 3-methyl-2-cyclohexen-1-one."}
