(+)-N,N′-Bis[(7,7-dimethyl-2-oxobicyclo­[2.2.1]heptan-1-yl)methyl­sulfon­yl]piperazine

In the title compound, C24H38N2O6S2, 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 approximate non-crystallographic twofold symmetry.
