d-Glucuronic acid is found widely in plants and animals. One of its functions is to detoxify poisonous HO-containing compoundsby reacting with them in the liver to form glucuronides.

Draw thestructure of the a- and b-glucuronides formed by the reaction of b-d-glucuronic acid and phenol.

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 WĂ¶hler 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? (b) What is a likely structure for ecgonine, neglecting stereochemistry? (c) What is a likely structure for cocaine, neglecting stereochemistry?
