Unlike most β-diketones, the following β-diketone has no detectable enol content and is about as acidic as acetone. Explain.

The final step in attempting to synthesize Laurene, a hydrocarbon isolated from the marine alga Laurencia glandulifera,involved the Wittig reaction shown. The product obtained, however, was not Laurene but an isomer. Propose a mechanism to account for these unexpected results.

How would you prepare the following ketones using an acetoacetic ester synthesis?

Sodium pentothal is a short-acting barbiturate derivative used as a general anesthetic and known as a truth serum in popular culture. It is synthesized like other barbiturates (see the Something Extra at the end of this chapter), using thiourea, (H2N)2C=S, in place of urea. How would you synthesize sodium pentothal?

Predict the product(s) of the following reactions:
