Oxa-6-azaspiro[3.3]heptane (174-78-7) video

Synthesis of the bicyclic spiro compound 2-oxa-6-azaspiro[3.3]heptane is presented. which this compound is often isolated as an oxalate salt, its isolation as a sulfonic acid salt yields a more stable and more soluble product. With these improved properties access to a wider range of reaction conditions with the spirobicyclic 2-oxa-6-azaspiro[3.3]heptane has been enabled.

1,3-Dipolar cycloaddition of benzylidenecyclopropane with various aldonitrones proceeds regioselectively giving good yields of 4-spirocyclopropane isoxazolidines. In the case of aldonitrones, bearing carbamoyl- or aryl-groups on the carbon atom, only the cis-isomer is formed. The compounds synthesized were tested for their virus-inhibiting activity.

Its chemecial description is: 2-oxa-6-azaspiro[3.3]heptane; 174-78-7; 2-oxa-6-aza-spiro[3.3]heptane; 2-oxa-6-azaspiro[3.3]heptane HCl; AC1Q1IDW; Spiro[oxetane-3,3′-azetidine]

Oxa-6-azaspiro[3.3]heptaneis a  useful synthetic intermediate in the preparation of epidermal growth factors, and it is insoluble in water.
