Organometallic complexes are useful tools in synthetic organic chemistry. We investigated a novel synthetic method for ring construction using organometallic complexes and synthesized natural products and biologically active substances using these methods. Metalacycles formed from an early transition metal and diene, enyne, and diyne are stable under the reaction conditions and they are easily converted into compounds with functional groups by the addition of various agents. We have developed a novel synthetic method of heterocycles from enyne and diene using Cp2ZrBu2. The total syntheses of (−)-dendrobine, (±)-mecembrane, and (±)-mecembrine were achieved using this procedure. To synthesize these natural products as a chiral form, a novel palladium-catalyzed asymmetric allylic amination was developed, and chiral 2-arylcyclohexenylamine derivatives were synthesized. From these compounds, the total syntheses of (−)-mesembrane, (−)-mesembrine, (+)-crinamine, (−)-haemanthidine, and (+)-pretazetine were achieved. By further development of this procedure, a chiral 2-siloxymethylcyclohexenylamine derivative could be synthesized and the novel synthesis of indole derivatives was developed from this compound. From this indole derivative, (−)-tsubifoline and (−)-strychnine were synthesized.
