Abstract
The intramol. Pd(II)-mediated cyclization of 1-allyl-2-indolecarboxamides leads to pyrazino[1,2-a]indoles through the conversion of the olefinic C-H bond into a C-N bond by reaction with an amide group. When operating on the allylamide, a domino process was obsd. with a double C-H functionalization. [on SciFinder (R)]
