text: Camphorsultam, also known as bornanesultam, is a crystalline solid primarily used as a chiral auxiliary in the synthesis of other chemicals with a specific desired stereoselectivity. Camphorsultam is commercially available in both enantiomers of its exo forms: (1R)-(+)-2,10-camphorsultam and (1S)-(−)-2,10-camphorsultam.
