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.
(a) Draw two different halo ketones that can form A by an intramolecularalkylation reaction. (b) How can A be synthesized by an acetoacetic estersynthesis?
Zingerone, a spicy-sweet component of cooked ginger, can be converted to its protected TBDMS ether A, as we learned in Chapter 20. How can A be converted to gingerol, a compound present in fresh ginger, using a directed aldol reaction as a key step?
