Cis-3,3-Dimethyl-3,3a,4,5,6,6a-hexa-hydro-1H-cyclo-penta-[c]furan-1,6-dione.

ABSTRACT: The bicyclic mol-ecule of the title compound, C(9)H(12)O(3), contains two five-membered rings with different functional groups, viz. a ketone and an ester. Both rings assume an envelope conformation. The mean planes of these functional groups form a dihedral angle of 60.7?(1)°. The crystal structure exhibits weak inter-molecular C-H?O inter-actions, which link the mol-ecules into zigzag chains extended in the [010] direction. The unit cell contains a racemic mixture of enanti-omers.

Project description:The title compound, C(16)H(17)NOS(2), consists of a carbazole skeleton with tetra-hydro-furan and dithiol-ane rings. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 1.57?(15)°. The cyclo-hexenone and tetra-hydro-furan rings have envelope conformations, while the dithiol-ane ring adopts a twist conformation. In the crystal structure, pairs of weak inter-molecular N-H?S hydrogen bonds link the mol-ecules into centrosymmetric dimers with R(2) (2)(16) ring motifs. Weak C-H?? inter-actions may further stabilize the structure.
