endocyclic enamide (2-azetine) to dichloroketene is described and constitutes a new entry to the synthesis of substituted azetidines. Preliminary studies concerning the Baeyer–Villiger oxidation of the [2+2] cycloadduct revealed an unusual regioselectivity. The synthesis of a new azetidine-3-carboxylic acid derivative from the [2+2] cycloadduct is also presented.
