How is (1S)-(+)-(10-Camphorsulfonyl)oxaziridine (CAS: 104322-63-6) typically synthesized?

(1S)-(+)-(10-Camphorsulfonyl)oxaziridine is usually synthesized by the reaction of camphorsulfonic acid with oxaziridine. This process involves the condensation of camphorsulfonic acid with an appropriate aldehyde or ketone under acidic conditions, followed by treatment with a reducing agent to form the oxaziridine ring. The reaction is typically carried out in the presence of a suitable catalyst to enhance the yield and selectivity.
