New Strategies for Bioactive Heterocyclic Compound Synthesis

The present book includes various methodologies for the synthesis of biologically significant heterocyclic compounds using several reusable heterogeneous catalysts such as aluminium nitride, nano-zinc oxide, lanthanum oxide, ytterbium triflate and montmorillonite-KSF clay under different conditions along with biological activity of some of the synthesized compounds. Chapter-1: Introduction. Chapter-2: Synthesis of 2, 4, 5-triaryl imidazoles, benzimidazoles and bis(indolyl)methanes. Chapter-3: Synthesis of 2, 3-dihydroquinazolin-4(1H)-ones ¿-amino phosphonates. Chapter-4: Lanthanum oxide as a catalyst for the synthesis of Hantzsch polyhydroquinolines and ytterbium triflate as a catalyst for the synthesis of dicoumarols. Chapter-5: Nano ZnO as catalyst for synthesis of pyranopyrazoles and furanones. Chapter-6: Synthesis and biological screening of some novel hydrazone derivatives.
