The present invention provides methods for chemically synthesizing naturally-occurring alkaloids, for example,
Flindersia
alkaloids, and their analogs and derivatives. Generally, the precursor borrerine is synthesized from tryptamine in the presence of an alkylating agent, an acylating agent and a reducing agent and dimerized in the presence of an acid, for example, tetrafluoroacetic acid, hydrochloric acid or acetic acid to yield the products. Analog and derivative compounds are produced by derivatizing one or more of the tryptamine, alkylating agent or acylating agent. Also provided are the synthetic alkaloids and derivatives and analogs thereof produced by the synthetic methods.

A biomimetic strategy for the synthesis of the antimalarial flindersial alkaloids is described. Flinderoles A, B, and C, desmethylflinderole C, isoborreverine, and dimethylisoborreverine were all synthesized in three steps from tryptamine. The key step is an acid-promoted dimerization of the natural product borrerine. This approach is thought to mirror the biosynthesis of these compounds.
