, p. 1068 - 1074 (2003)
The structures of the adducts derived from the reactions of substituted ketenes with dihydropyridine derivatives have been clarified by single crystal X-ray analyses and the formation mechanism is discussed on the basis of the reaction-path calculations by semiempirical and density functional theory (DFT) molecular orbital methods.
Stereoselective synthesis of highly functionalised tricyclic β-lactams via intramolecular nitrilimine cycloaddition
Del Buttero, Paola,Molteni, Giorgio
, p. 1319 - 1321 (2007/10/03)
The novel azeto[2′,1′:1,2]pyrrolo[3,4-c]pyrazole skeleton has been obtained in both racemic and enantiopure forms by means of intramolecular cycloaddition of nitrilimines 6. Fully stereoselective cycloadditions were obtained, giving tricyclic β-lactams 7
