Abstract

magnified image

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.
