Direct organocatalytic synthesis of enantiopure succinimides from β-lactam aldehydes through ring expansion promoted by azolium salt precatalysts

A single-step catalytic ring expansion approach from 4-oxoazetidine-2- carbaldehydes to enantiopure succinimides has been achieved by the use of a base (DBU) and a thiazolium salt precatalyst. The Royal Society of Chemistry.
