The synthesis of several 2-aza-bicycloheptan-6-ones has been achieved in a regiospecific manner through a cycloaddition reaction between five-membered cyclic enecarbamates and enamides and free ketenes.The synthetic potential of this new meth

N-Ethoxycarbonylmethyl Geissman-Waiss lactone ((+/-)-2) was easily synthesized from bis-lactone (3), and an unexpected epimerization of γ-butenolactone was observed in the process of asymmetric synthesis of 2.
