Abstract
(1S,2-exo)-1-[(N,N-Dicyclohexylamino)sulfonylme-thyl]-7,7-dimethylbicycl o[2.2.1]heptan-2-yl [2R(2alpha,-3beta,5beta,6alpha)]-tetrahydro-2,5,6-trimethyl-4-oxo-2H-py- ran-3-carboxylate, C31H51NO6S, has an asymmetric unit containing two unique but similarly conformed molecules (A and B). In molecule A the cyclohexyl rings are free to crystallize in either of the approximately coplanar conformations. whereas in molecule B only one conformation is allowed. The N atoms in each molecule have approximately planar geometries, as expected from previous related structures. The tetrahydropyranone ring adopts the chair conformation with all substituents equatorial.
