A one-step synthesis of azetidin-3-ones by intramolecular cyclization of 1-diazo-3-arenesulfamoylalkan-2-ones was developed.The yield of cyclic product increases to 70percent in the presence of an alkyl or benzyl substituent in the hydrocarbon chain of the diazoketone.The structure of N-tosyl-2-ethylazetidin-3-one was studied by x-ray diffraction analysis and it was shown that the four-membered ring has 15 deg inflection.
