Practice Problem H.5
Many alkaloids appear to be synthesized in plants by reactions that resemble the Mannich reaction (Section 19.8). Recognition of this (by R. Robinson in 1917) led to a synthesis of tropinone that takes place under “physiological conditions,” that is, at room temperature and at pH values near neutrality. This synthesis is shown here (and discussed in “Why These Topics Matter” at the end of Chapter 19). Propose reasonable mechanisms that account for the overall course of the reaction.
