The first total synthesis of spirobacillene A, an indole alkaloid isolated from Lysinibacillus fusiformis, is reported. A Lewis acid mediated spirocyclization of an anisole derivative onto a tethered ynone was used as a key step, drawing inspiration from a potential biosynthesis of the natural product.

The first totalsyntheses of spirobacillenes A and B were achieved concisely. The key transformation leading to spirobacillene A features a biomimetic intramolecular phenol-enol oxidative coupling reaction, and that leading to spirobacillene B highlights a bio-inspired intramolecular indole-ketone enolate oxidative coupling reaction.
