We have developed a new catalytic method for the one-pot, cascade synthesis of unsymmetrical secondary amines via the reductive amination of aryl nitriles with nitroalkanes using a PdPt-Fe3O4 nanoparticle (NP) catalyst. The use of a bimetallic catalyst resulted in enhanced reactivity and selectivity compared to that of either monometallic Pd-Fe3O4 or the Pt-Fe3O4 NP catalyst. Using this bimetallic catalytic system, we were successful in the synthesis of various unsymmetrical secondary amines under mild conditions. However, aryl nitriles containing an electron-donating substituent were rather resistant to the reductive amination, and when hexafluoroisopropanol (HFIP) was used as a co-solvent, the reaction selectivity and yield for unsymmetrical secondary amines increased dramatically. Using the catalyst system, one-pot, gram-scale synthesis of indole was possible from 2-nitrophenylacetonitrile. Due to the magnetic property of the Fe3O4 support, the bimetallic catalyst could easily be recycled using an external magnet at least four times.

A new series of 4-N-(substituted benzyl)-2-phenyl-N-propylquinazolines were synthesized. The structures of the synthesized compounds were confirmed by IR, 1H NMR, 13C NMR and mass spectral analysis. All the synthesized compounds were screened for their analgesic and anti-inflammatory activity. Among the synthesized compounds 5c, 5h and 5o exhibited significant analgesic activity at 60 and 90 minutes reading, while compounds 5g, 5k and 5l exhibited significant anti-inflammatory activity at 3rd and 4th hr reading.

A robust and reliable method has been developed for reductive amination of primary amines with various aldehydes and ketones using Zn(ClO4) 2.6H20 as a catalyst. [In-H] generated in situ via a combination of InCl3 and Et3SiH is employed as an effective reducing system. A variety of secondary amines can be synthesized in a one-pot procedure in excellent yields.
