Synthesis of fused polycyclic nitrogen-containing heterocycles via cascade cyclization

Saha, Biswajit,Kumar, Rishi,Maulik, Prakash R.,Kundu, Bijoy

, p. 2765 - 2769 (2007/10/03)

A novel strategy for the synthesis of fused polycyclic-nitrogen containing heterocycles via cascade cyclization is described. The methodology involves condensation of 1-(2-aminophenyl)-9H-β-carboline-3-carboxylic acid amide with isothiocyanates followed b
