An efficient and eco-friendly synthetic route for Friedländer quinoline synthesis of polysubstituted quinolines is described. This green chemical method starts from various 2-aminobenzophenones and mono- or dicarbonyl synthons and uses reusable Nafion NR50 material as a solid catalyst in ethanol undermicrowaveirradiation. The protocol has a high generality of functional groups and provides the desired

This study describes an efficient protocol for the preparation of substituted 2,4-diaryl-3-sulfonylquinolines from functionalized 2-aminobenzophenones and aromatic β-ketosulfones by using p-toluenesulfonic acid monohydrate under microwave irradiation. In this atom-economical synthetic route, a series of pharmaceutically active 3-arylsulfonylquinolines with good functional group tolerance are prepared

in vitro evaluation of benzo-fused benzodiazepines 1-6 are described. These "molecular yardsticks" were employed to probe the spatial dimensions of the lipophilic pocket L2 in the benzodiazepinereceptor (BzR) cleft and to determine the effect of occupation of L2 with respect to agonist activity. Of the new analogs synthesized, the 7,8-benzo-fused benzodiazepine 6 displayed moderately high affinity
