Name___________________________________ C341 Workshop Section____________________ Workshop 6 Questions 1. Aspartame was discovered in 1965 by James M. Schlatter, who had synthesized the compound in the course of producing an antiulcer drug candidate. He accidentally discovered its sweet taste when he licked his finger, which had become contaminated with aspartame. Identify the carboxylic acid, ester, amine, and amide functional groups in aspartame. Mark the most acidic proton in the compound and estimate its pKa, using Table 1.7. HO N H O NH 2 O O OCH 3 2.

By assuming that the heat of combustion of the cis- isomer was larger than the trans, structural assignments were made many years ago for the steroisomeric 2-, 3-, and 4-methylcyclohexanols. This assumption is valid for two of the steroisomeric pairs, but not for the other. For which pair of steroisomers is the assumption incorrect? Why? 4. Different reagents and conditions are used to convert secondary alcohols or tertiary alcohols to alkyl halides. Specify appropriate reagents for the following conversions and explain, in mechanistic terms, why different reagents and conditions are required. OH Cl OH Cl (a) (b)...
