A simple and atom-economical one-step protocol is described for the synthesis of biologically valuable 3-isoquinuclidones. The method proceeds from the simple starting materials, α-acyl N-arylcinnamamides, and can be performed under mild conditions in the presence of tBuOK. The key steps of this process are the double Michael addition reaction of a Nazarov-like reagent and the subsequent intramolecular

is presented for the synthesis of polysubstituted 4-pyridones and 2-pyridones from beta-keto amides. A variety of beta-keto amides are used in this approach, and a wide range of functionalized 4-pyridones and 2-pyridones were obtained in good to excellent yields. When employing the N-aryl beta-keto amides as the substrates in this protocol, 4-pyridones are resulted, however, when using N-aliphatic-substituted
