The reaction of oxime‐tethered 1,6‐enynes with a cationic gold(I) catalyst demonstrates a great potential for the synthesis of a range of heterocycles in a diastereospecific fashion. The control of the configuration of the oxime and the alkene of the enyne moiety is the key to selectively obtain dihydro‐1,2‐oxazines, isoxazolines or dihydropyrrole‐N‐oxides as single diastereoisomers.
