    Novel series of 8H-quinazolino[4,3-b]quinazolin-8-ones via two Niementowski condensations
    摘要:
    Efficient microwave-assisted multi-step synthesis of 8H-quinazolino[4,3-b]quinazolin-8-one was investigated. The synthesis involved two Niementowski condensations from anthranilic acids. Homogeneous or heterogeneous conditions were studied with the aim to develop convenient syntheses of the desired compounds. (C) 2003 Elsevier Science Ltd. All rights reserved.

  • Copper-Catalyzed One-Pot Synthesis of Quinazolinones from 2-Nitrobenzaldehydes with Aldehydes: Application toward the Synthesis of Natural Products
    作者:Subrata Sahoo、Shantanu Pal
    DOI:10.1021/acs.joc.1c02343
    日期:2021.12.17
    A novel, efficient, and atom-economical approach for the construction of quinazolinones from 2-nitrobenzaldehydes has been unveiled via copper-catalyzed nitrile formation, hydrolysis, and reduction in one pot for the first time. In this reaction, urea is used as a source of nitrogen for nitrile formation, hydrazine hydrate is used for both the reduction of the nitro group and the hydrolysis of nitrile

    base‐catalyzed isomerization of 13H‐quinazolino[3,4‐a]quinazolin‐13‐ones to 8H‐quinazolino[4,3‐b]quinazolin‐8‐ones in excellent yields (90–95%) has been reported. The differences in the infrared and nuclear magnetic resonance (1H & 13C) data of these isomeric fused quinazolinoquinazolinones afford a useful method for distinguishing between the two series. These analogs showed moderate anticancer activity (EGFR‐TK
