Pyrrolidine, Piperidine, and Pyridine Alkaloids

1968
There are only a few simple pyrrolidine alkaloids found in nature, although pyrrolidine (or pyrrole) rings combined into larger structures are relatively common (e.g., in the indole alkaloids). Methylated derivatives of proline or hydroxyproline could be called alkaloids but are here placed with protoalkaloids in Chapter 2; β-methylpyrroline is ...
