Herein, γ-lactam derivatives are obtained in high yield via highly regioselective intramolecular Csp3–H insertion reactions of α-diazoacetamides catalyzed by a rac-Ru(II)–Pheox complex. The catalytic system is applicable to a wide range of diaz
Cyclisation at very high temperature. Thermal transformations of N-alkyl and N, N-dialkyl amides of α,β-unsaturated acids into mono- and bicyclic heterocycles under FVT conditions

Cyclisations of N-alkyl and N,N-dialkyl cinnamic amides to the corresponding pyrrolidin-2-ones under the conditions of flash vacuum thermolysis (FVT), are described. It was found that these reactions proceed at 950-1000 °C affording in various yields the

Novel cyclisations of N-alkyl and N,N-dialkyl cinnamic amides to the corresponding pyrrolidin-2-ones under the conditions of flash vacuum thermolysis, are described. It was found that this reaction proceeds at 950-1000°C affording a mixture of isomeric pyrrolidin-2-ones in various yields. Two possible mechanisms are proposed for the process.
