We describe the design and execution of a novel synthetic route to the tricyclic core of haliclonin A, a tetracyclic marine natural product. The approach features Bachi’s thiol-medicated free radical cyclization of alkenyl isocyanide to build the bridged ring system, and ring-closing metathesis (RCM) reaction to form the macrocycle. Execution of the synthetic plan ultimately resulted in a diazatricyclic compound. By means of 2D NMR techniques, the structure of this compound was revealed to an unexpected product8. Analysis of the synthetic pathways allowed concluding that the unexpected product is a result of an “unexpected” migration of olefinic bond during dioxolanation of the 2-cyclohexenone derivative7. This investigation also resulted in a concise construction of the functionalized hexahydro-1H-isoindole-1,5(4H)-dione12and the macrocyclic tricyclic ring system8.
