N-heterocyclic carbene catalyzed ring expansion of 4-formyl-β-lactams: Synthesis of succinimide derivatives

N-Heterocyclic carbene (NHC) has been employed as an efficient catalyst for ring expansion of 4-formyl-β-lactams, allowing the facile synthesis of succinimide derivatives. This organocatalytic process features readily availability of the catalyst, low cat

Diastereoselective [2+2]-cycloaddition reactions of unsymmetrical cyclic ketenes with imines: Synthesis of modified prolines and theoretical study of the reaction mechanism

The synthesis of enantiomerically pure modified proline derivatives was achieved by using spiro β-lactams as starting material that were prepared in turn by the [2+2]-cycloaddition of unsymmetrical cyclic ketenes with optically active imines. A theoretica
