Coinage metals-catalyzed cascade reactions of aryl alkynylaziridines: Silver(I)-single vs gold(I)-double cyclizations

Alkynylaziridines carrying an aryl group could be efficiently converted into aminoallenylidene isochromans, isoquinolines, or tetrahydronaphtalenes with silver(I) salts and into 1-azaspiro[4.5]decane derivatives with gold(I) complexes. Mechanistic investi

Gold(i)-catalyzed rearrangement of aryl alkynylaziridines to spiro[isochroman-4,2′-pyrrolines]

Alkynylaziridines carrying an aryl group could be efficiently converted to spiro[isochroman-4,2′-pyrrolines] with gold salts as catalysts. This new rearrangement involved a Friedel-Crafts type intramolecular reaction followed by cyclization of the aminoallene intermediate, both initiated by the dual σ and π Lewis acidities of gold.
