| [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. |
