Participants

Reaction Steps

Zinc dust (2.0 g, 0.03 mole) was slowly added with cooling to a solution of 5.0 g (0.011 mole) of cis-3-azido-4-oxo-2-p-toluenesulfonyloxymethylazetidine in 50 ml of 50% aqueous acetic acid. The reaction mixture was stirred for 30 minutes and filtered. The solids were washed with water and the filtrate was saturated with hydrogen sulfide, filtered and concentrated to near dryness. The residue was dissolved in ethyl acetate-water and the pH was adjusted to 8.0 by addition of sodium carbonate and sodium hydroxide solutions. The layers were separated and the aqueous phase was extracted twice with ethyl acetate. The extracts were combined, dried (MgSO4) and evaporated to dryness to give the title compound.
