Synthesis, characterization, antioxidant, DNA binding and density functional studies of novel bisamides

p-Toluenesulfonic acid-promoted organic transformations for the generation of molecular complexity

“…Synthetically important intermediate symmetrical bisamides 9 have been prepared by Hassanabadi et al through a three-component coupling approach with 10 mol% of p -TSA as a catalyst. 10 A series of liquid aromatic aldehydes with either electron withdrawing or electron donating group was coupled with 2 equivalents of different amides in solvent-free conditions at around 30 °C under sonication (Scheme 6).…”
