Description

Application

(1S)-(+)-(10-Camphorsulfonyl)oxaziridine can be used:

• To convert prochiral ketone enolates into optically active α-hydroxy ketones via enantioselective asymmetric oxidation.
• In the synthesis of thymidine oligonucleotides connected through pyrophosphates.
• In the asymmetric synthesis of proton pump inhibitors like (R)-Rabeprazole sodium and (R)-Lansoprazole sodium from the corresponding DBU salt of prochiral sulfide.
• In the preparation of phosphonoacetate and thiophosphonoacetate oligodeoxynucleotides by oxidizing the corresponding phosphinoacetate.
