Palladiumcatalysed processes involving sequential cyclisation of aryl iodides onto proximate allenes with capture by NaN3 (and NaO2SPh) followed by a 1,3-dipolar cycloaddition reaction utilizing DMAD, methyl propiolate and norbornadiene are described. When utilising the latter, the sequence can be carried out as a one-pot protocol which terminates with a retro Diels-Alder reaction.
