[Uses]

1-Boc-3-azetidinone can be used for the preparation of antibacterial aminoglycoside analogs.
[General Description]

tert-Butyl 3-oxoazetidine-1-carboxylate is moisture sensitive and incompatible with oxidizing agents. This chemical can cause skin irritation and severe eye irritation. 
[Synthesis]

The traditional preparation method of tert-Butyl 3-oxoazetidine-1-carboxylate is mainly to oxidize the hydroxyl on an aza ring into ketone. For example: 3-azetidinium alkoxide, di-tert-butyl dicarbonate and sodium bicarbonate in dioxane: stirring the mixture of water for 15 hours to obtain 3-hydroxyazetidine-1-carboxylic acid-1, 1-dimethylethyl ester; dissolving 3-hydroxyazetidine-1-carboxylic acid-1, 1-dimethyl ethyl ester in ethanedioyl chloride and dichloromethane, adding DMSO and triethylamine, stirring at room temperature for 15 hours to obtain tert-Butyl 3-oxoazetidine-1-carboxylate.
