A facile and efficient AgI‐catalytic approach is reported for the first time to synthesize β‐oxo amides from β‐oxo esters a with broad substrate scope in good to excellent yields. Crossover and in situ NMR studies confirmed that the reaction occurred through a new pathway and not by the traditional condensation reaction. The key advantages of this method are the readily available starting materials, the air‐stable reaction, the simple protocol, and the environmental friendliness.

A simple method has been developed for the synthesis of fused isoindolines via a cascade HDDA approach catalyzed by Fe2(CO)9.

A sustainable and simple Au(I) catalytic system to synthesise 8-oxabicyclo[3.2.1]oct-2-enes and 9-oxabicyclo[3.3.1]nona-2,6-dienes from enynol via oxonium/Prins-type cyclization is described. The key advantages of this reaction are selectivity, good functional group tolerance and a new approach for synthesis of oxabicyclic and oxatricyclic systems.

The efficient conversion of aryl and alkyl β‐keto esters to N‐aryl and N‐alkyl amides is developed using AgOTf as catalyst.
