In the title compound, C 24 H 38 N 2 O 6 S 2 , which was synthesized from (+)-10-camphorsulfonic acid chloride and piperazine, the central piperazine ring adopts a chair conformation. The two camphorlsulfonyl groups are bound to the piperazine N atoms in equatorial positions. The molecule has approx
