Intramolecular Diels-Alder reaction of 3-formimidoylindoles having olefinic substituents at the 1-position of the indole ring gave stereoselectively fused pyridoindole compounds.Double bond migration from 2,3,3a,4,12,12a,12b,12c-octahydrobenzindolonaphthyridin-11(1H)-ones (4) to 2,3,3a,4,5,12,12a,12b-octahydrobenzindolonaphthyridin-11(1H)-one (5) was performed using 10percent Pd-C as a catalyst.

The halogen atom transfer radical cyclization (HATRC) has been evaluated on N-(indolylmethyl)trichloroacetamides under Cu(I)Cl catalysis using nitrogen containing ligands. The ring closure leads to the formation of 3,3-spiro-3H-indoles in moderate to good
