 intramolecular pd - catalyzed alkene 
 carboamination reactions of 
 substituted 2-allyl - n-(2-bromobenzyl)anilines are 
 described . 
 the substrates for these reactions are generated in two 
 steps from readily available 2-allylanilines and 2-bromobenzaldehyde 
 derivatives . 
 the transformations afford substituted tetrahydroindoloisoquinolines , 
 an uncommon class of fused bicyclic heterocycles , in good yield . 
 the 
 mechanism of these transformations is described , and a model that 
 accounts for the observed product stereochemistry is proposed .
