AbstractAn aluminum triflate‐catalyzed intramolecular reaction sequence involving protonation and Mannich‐like nucleophilic addition of indoles toward the concise construction of the tetrahydropyrido[1,2‐a]indol‐6‐one skeleton is reported. This new reaction pattern employs a carbon atom as nucleophile to form a CC bond which bears one or even two quaternary carbons and leads to the dearomatization of indoles with high atom economy.magnified image

The first totalsynthesis of the indole alkaloid mersicarpine is reported. Key steps include a beta-dicarbonyl radical cyclization, as well as an oxidation of the benzopyrrole moiety to establish the masked 1,2-dicarbonyl functionality. An X-ray crystal structure and discussion of the 1H NMR behavior of the natural product are also presented.
