چکیده
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⋯π inter-actions may further stabilize the structure.

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 ...

Chiral 3,3a,5,9b-tetrahydro-2H-furo[3,2-c][2]benzopyrans (TFBs) were synthesized and some of them were found to be herbicidally active against annual paddy weeds through intensive structure–activity relationship studies. These compounds were synthesized from D-glucose, which was used as a natural chiral source. This was the result of a series of studies based on the findings that certain benzyl...
