Abstract: Abstract Nitrogen-containing polycyclic core 5-phenylnaphtho[1,2,3,4-lmn] phenanthridine and its nitro-functionalized positional isomers were synthesized using Pictet-Spengler reaction between hexaalkoxytriphenylene-1-amine and various aryl aldehydes. The hexagonal columnar phase was observed in all the synthesized novel compounds. Mesomorphic… read more here.

Abstract: A ruthenium(ii)-catalyzed cross-ring (5+1) annulation between 2-aminobiphenyls and activated olefins is disclosed for succinct synthesis of valuable phenanthridine scaffolds. The protocol avails a common organic functional group, free amine, as a directing group and represents… read more here.
