The asymmetric unit of the title compound, C54H64O12S4, consists of one half of the mol-ecule, which is located on an inversion centre. The heterocyclic six-membered ring adopts a distorted envelope conformation with the spiro C atom as the flap. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds with an R (2) 2(14) motif, forming a chain along the b-axis direction. ...[more]
