  A new rapid multicomponent domino reaction for the formation of functionalized benzo[h]pyrazolo[3,4-b]quinolines

  摘要：

  建立了一种新的多组分多米诺反应，用于快速和区域选择性合成高度官能化的苯并[h]吡唑并[3,4-b]喹啉。该反应可在微波辐照下，使用易得且廉价的底物，在10-26分钟内完成。对22个例子，实现了61-91%的良好至优异的化学产率和完全的区域选择性。由于产物直接从反应溶液中沉淀出来，避免了繁琐的后处理步骤。所得苯并喹啉可通过与苯-1,2-二胺在微波辐照下反应，容易地转化为喹喉并苯并[h]异噁唑并[5,4-b]喹啉类似物。通过X射线分析，结构归属得到了含糊的确证。为此新型多组分多米诺过程提出了一种新的机理。

  The L-proline-catalyzed synthesis of 7-(aryl)-8-methyl-10-phenyl-5H-benzo[h]pyrazolo-[3,4-b]quinoline-5,6(10H)-diones via the four-component sequential reaction of phenylhydrazine, 3-aminocrotononitrile, substituted benzaldehydes and 2-hydroxynaphthalene-1,4-dione is described. This “on water” protocol proceeds in high atom economy and leads to the generation of two rings, together with two C–C, one C–N and two CN bonds in a single operation. The environmental advantages of the method include short reaction time, excellent yield, easy work-up, and the absence of extraction and chromatographic purification steps.

  A new multicomponent domino reaction for rapid and regioselective synthesis of highly functionalized benzo[h]pyrazolo[3,4-b]quinolines has been established. The reaction can be conducted by using readily available and inexpensive substrates under microwave irradiation within short periods of 10–26 min. Good to excellent chemical yields (61–91%) and complete regioselectivity have been achieved for 22 examples. Tedious work-up procedure can be avoided due to the direct precipitation of products from the reaction solution. The resulting benzoquinolines have been readily converted into quinoxaline-fused benzo[h]isoxazolo[5,4-b]quinoline analogues by treating with benzene-1,2-diamine under microwave irradiation. The structural assignment has been ambiguously confirmed by X-ray analysis. A new mechanism has been proposed for this new multicomponent domino process.
