The structures of the aldol condensation products of each of the given compound in the problem 21.9 are to be drawn. Among these given aldehydes , the one that does not undergo aldol condensation is to be identified and the reason is to be explained. Concept Introduction: > In the presence of either acid or base, the two molecules of aldehydes or ketone that present alpha hydrogen are react and forms β-hydroxy carbonyl compounds, this reaction is known as aldol addition reaction. > The dehydration of aldol addition product results in the formation of α,β- unsaturated ketone or aldehyde. Such a reaction is known as aldol condensation reaction.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

β-Vetivone is isolated from vetiver, a perennial grass that yields a variety ofcompounds used in traditional eastern medicine, pest control, and fragrance. In one synthesis, ketone A is converted to β-vetivone by a two-step process: Michael reaction, followed by intramolecular aldol reaction. (a) What Michael acceptor is needed for the conjugate addition? (b) Draw a stepwise mechanism for the aldol reaction, which forms the six-membered ring.
