摘要
Gold-catalyzed aminoaromatizations 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 the synthetic utility of these reactions. (Figure presented.).
