چکیده
The crystal structure of the title compound, C(15)H(17)NO(2), contains two nearly identical but crystallographically independent molecules, each with a double bond connecting an azabicyclic ring system to a 3-methoxybenzylidene moiety. The space group is triclinic P-1. The benzene ring is twisted by 18.44 (5) and 22.35 (4) degrees with respect to the plane of the double bond connected to the azabicyclic ring system for the two molecules. In addition to C-H...pi interactions, molecules are held together in the solid state by van der Waals interactions.

The title compounds, C22H20N2O3S, (I), and C22H22N2O3S, (II), crystallize in space groups P-1 and P2(1)2(1)2(1), respectively. The indole rings are planar and the benzene ring of the phenylsulfonyl group makes a dihedral angle with the mean plane of the indole ring of 90.2 (2) degrees in (I) and 94.0 (2) degrees in (II). In both molecules, the double bond connecting the aza-bicyclic and indole ...

Radiation therapy combined with adjuvant hyperthermia has the potential to provide outstanding local-regional control for refractory disease. However, achieving therapeutic thermal dose can be problematic. In the current investigation, we used a chemistry-driven approach with the goal of designing and synthesizing novel small molecules that could function as thermal radiosensitizers. (Z)-(+/-)-...
