Gold (I)-triflimide (AuNTf(2))complexes of H-KITPHOS and o-MeO-KITPHOS have been prepared and shown to be efficient catalysts for a range of intramolecular cyclisations to afford phenols, acylindenes, alkylidene oxazoles, tetrahydropyrans and lactones, in the majority of cases these catalysts are superior to those previously reported.
