Gold‐catalyzedaminoaromatizations of 1,n‐diynes with anthranils afforded 1‐amino‐2‐napthaldehyde derivatives efficiently. In this reaction sequence, anthranils preferably attack at gold‐coordinated prop‐3‐yn‐1‐ols to generate α‐imino gold carbenes that enable subsequent cyclizations with the other alkynes. Chemical functionalizations of the resulting 1‐amino‐2‐napthaldehydes are presented to manifest
