Abstract Catalyzed by SmI3 β-diketones and β-ketoesters condense with aldehydes to give benzylidene substituted β-diketones and β-ketoesters at room temperatures in fair yields.
A new formal [1 + 2 + 3] annulation of o-alkenyl arylisocyanides with α, β-unsaturatedketones under metal-, base-, and acid-free conditions is disclosed. This domino reaction provides a general protocol for the efficient and practical synthesis of a wide range of carbazole derivatives from readily available starting materials in a single operation. Furthermore, this methodology was used as the key

A facile synthesis of benzonitriles via a base‐promoted tandem cyclization reaction of α,β‐unsaturated enones having electron‐withdrawing group (EWG) and 2‐acyl‐acrylonitriles was developed. This new synthetic method to access benzonitriles is suitable for a wide range of substrates. A plausible reaction mechanism is proposed on the basis of previous literature and our own investigations.
