Quinapril (trade name Accupril) is used to treat high blood pressure andcongestive heart failure. One step in the synthesis of quinapril involvesreaction of the racemic alkyl bromide A with a single enantiomer of theamino ester B.
Given the structure of quinapril, which one of these two products isneeded to synthesize the drug?
24.82 When the compound shown here is heated, ethene gas
is evolved and a product with the formula C14H3O2 is
formed. The 'H NMR and 13C NMR spectra of C14H8O2
are shown below. (There are two signals >150 ppm in
the 13C NMR spectrum. Recall that the 13C NMR signal
at 77 ppm is from the CDCI3 solvent.)
(a) Draw the structure of C,14H3O2.
(b) Draw the mechanism that accounts for its formation.
(c) What is the main driving force that favors the products of this reaction?

- As far back as the 16th century, South American Incas chewed the leaves of the coca bush, Erythroxylon coca, to combat fatigue. Chemical studies of Erythroxylon coca by Friedrich Wöhler in 1862 resulted in the discovery of cocaine, C17H21NO4, as the active component. Basic hydrolysis of cocaine leads to methanol, benzoic acid, and another compound called ecgonine, C9H15NO3. Oxidation of ecgonine with CrO3 yields a keto acid that readily loses CO2 on heating, giving tropinone. (a) What is a likely structure for the keto acid?
