  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.

  日期：2011.8

  Two novel general experimental procedures for preparation of neutral monomethine cyanine dyes without using a basic agent have been developed. The procedures allow synthesis of cyanine dyes by reaction of substituted methylthio aromatic heterocycles with different quaternized nitrogen containing heterocycles by simple melting or by their reaction in acetic anhydride for short reaction times. The proposed

  已经开发出两种新颖的不使用碱性试剂制备中性单次甲基花青染料的常规实验程序。该程序允许通过简单的熔融或通过它们在乙酸酐中的短反应时间的反应，使取代的甲硫基芳香族杂环与不同的季铵化的含氮杂环反应来合成花青染料。所提出的方法用途广泛，因为可以使用多种不同的起始原料。
