    • Interestingly, recent studies by Weinreb's group have shown that a novel variation of the Heck reaction can be applied on substrates which contain a vinyl halide, an olefin and a nucleophile leading to various carbo- and heterobicyclic compounds. Nevertheless, it is important to note that the Weinreb's three component reactions were never applied to substrates which could be involved in the Wacker-type reaction: (a) Nylund, C.S.; Klopp, J.M.; Weinreb, S.M.
