methodological development of a series of domino or cascade reactions affording a series of N-heterocycles is described. The rapid formation of these ring systems is in each case associated with the incorporation of a Heck reaction at either an early or a late stage of the domino process. A range of catalytic conditions and substrate modifications for optimisation of domino Tsuji–Trost/Heck, Buchwald–Hartwig/Heck

A series of methods for palladium-mediated single-step and domino Tsuji–Trost/Heckreactions are described. These methods are applied to the synthesis of both 3-benzazepines and azepino[4,5-b]indoles in the category of complex 6-7-6 and 6-5-7 ring heterocycles. In addition, a domino Heck/Heck sequence of reactions that produces the azepinobenzindolizine tetracyclic ring system from N-diallylated precursors
