Abstract

Ynamides bearing a tethered allyl sulfoxide undergo a gold-catalysed cycloisomerisation to afford 2-carboxylic amide tetrahydrothiophenes and their benzofused analogues. The reactions are initiated by a formal 7-endo-dig cyclisation and accommodate a range of different substituents. The use of N-allyl ynamides provided a route into novel spirocyclic ε-lactam structures.
