2. Draw the products for the following aldol reactions: NaOH NaOH H + (two possible combinations)...
Aldol condensations between different carbonyl reactants are called crossed or mixed reactions. In most there are several possible products. Beta-elimination of water usually occurs. An example of a crossed aldol reaction is shown This particular reaction has two possible aldol products. Draw both but don't include the dehydrated products. Suggest a way to optimize the formation of either of the products above.
The following aldol reaction can produce 4 products. Select the structure that is not a possible product of the following reaction. (5 points) NaOH بانت H H HO CH CH OH بابا بابا H HC A B C D E
