Organocatalytic ring expansion of β-lactams to γ-lactams through a novel N1-C4 bond cleavage. Direct synthesis of enantiopure succinimide derivatives

(Chemical Equation Presented) Tetrabutylammonium cyanide (20 mol %) catalyzes ring expansion of 4-(arylimino)methylazetidin-2-ones 2 to 5-aryliminopyrrolidin-2-ones 3 through a novel N1-C4 bond cleavage of the β-lactam nucleus. New, efficient one-pot prot
