Enantiopure 4-formylazetidin-2-ones la-d have been used as building blocks for the synthesis of 4-aminopiperidin-2-ones 6a-d in 28-39% overall yields. The synthesis involves ring expansion of azetidinone 4a-d via methanolysis followed by a reductive

Azetidin-2-one, a four-membered cyclic lactam (beta-lactam) skeleton has been recognised as a useful building block for the synthesis of a large number of organic molecules by exploiting the strain energy associated with it, in addition to its use in
