Procedure

A mixture of 500 mg (2.5 mmole) of cis-3-azido-2-(2,2-dimethoxyethyl)-4-oxoazetidine in 10 ml of 5% HCl and 10 ml of dioxane was stirred at 35° for 1/2 hour. The mixture was diluted with water and extracted with 50 ml of benzene. The aqueous phase was saturated with brine and extracted 10 times with 50 ml of ethyl acetate. The ethyl acetate extract was dried over magnesium sulfate and evaporated to dryness. The residue was titurated with ether to give the desired aldehyde, 235 mg (60%), mp 73°-78°.
