of substituted quinolin-4(1H)-ones or enaminones is presented. A base-promoted insertion of ynones into the C–N σ-bond of amides is the key step in this process, which provides the corresponding aminoacylation products in good to high yields. Quinolin-4(1H)-ones are selectively formed via the subsequent N-cyclization pathway in the cases of ynones bearing an ortho-bromo-substituted aryl ring. Easily
