The domino reaction between ammonium salt AS 4 and aldimine AD 2, in the presence of Cs2CO3, yielding aziridine trans‐AZ 7 was studied within the Molecular Electron Density Theory at the B3LYP (PCM, DCM)/def2‐TZVP//B3LYP (PCM, DCM)/GenECP computational level. This domino reaction begins with the proton abstraction from AS 4 by Cs2CO3 yielding ammonium ylide AY 5. The subsequent nucleophilic attack...
The regio and stereoselective transformation of trans 1,2,3-trisubstituted aziridines into trans oxazolidin-2-ones takes place in good yield. However, the cis configuration at C2 and C3 in monocyclic aziridines is a limiting factor for this transformation. Ab initio calculations show that while the ring-opening process assisted by iodide is regioselective, the subsequent ring-closure is responsible...
