Acid cyclization of 4-(indol-1- and -3-ylmethyl)-2-cyanopiperidines 5̃ led to the bridged tetracyclic indole- systems 1̃ and 2̃. The required 2-cyanopiperidines 5̃ were prepared by catalytic hydrogenation of 2-cyano-1,2,3,6-tetrahydropyridines 4̃ and by DIBAL reduction of lactams 7̃ followed by cyanide ion addition to the intermediate enamine.
