In this paper we report our studies on 6-endo- versus 5-exo-trig cyclizations of 2-hetero-1-methylene-1,2,3,4-tetrahydroisoquinolines. This can be used for the construction of a variety of functionalized five- or six-membered heterocyclic rings.

A series of palladium (and in some cases rhodium) catalysed regiospecific 5-exo-, 6-endo- and 6-exo-trig cyclisations of aryl iodides and vinyl bromides onto proximate alkenes or heteroaromatic rings (indole, pyrrole) lead to a wide variety of fused ring
