arylation was successfully employed in the synthesis of azafluoranthene alkaloids for the first time. Direct arylation reactions on a diverse set of phenyltetrahydroisoquinolines produces the indeno[1,2,3-ij]isoquinoline nucleus en route to a high yielding azafluoranthene synthesis. The method was used as a key step in the efficientpreparation of the natural products rufescine and triclisine. As demonstrated

A short and new synthesis of the non-phenolic azafluoranthene alkaloid triclisine utilizing the photocyclization of 1-(2-halophenyl)-3,4-dihydro-6,7-dimethoxyisoquinolines as a key step has been described. (c) 2005 Elsevier Ltd. All rights reserved.
Divergent Total Syntheses to Azafluoranthene and Dehydroaporphine Alkaloids
Facile divergent total syntheses for azafluoranthene and dehydroaporphine alkaloids have been successfully developed. A common intermediate, a biarylsulfonamide-protected amino aldehyde, underwent either a cascade or a stepwise cyclization to furnish a tetracyclic skeleton related to the azafluoranthene alkaloids. Natural products, triclisine and telitoxine, were prepared to illustrate the use of this
