The efficient synthesis of a variety of substituted 2-aryl-2,3-dihydro-1H-perimidines using Zn-catalysis is reported. A series of 2,3-dihydroperimidines with various functional groups have been isolated in high yield by simple filtration from the reaction mixture. The new compounds have been fully characterized by spectroscopic and spectrometric analyses and in some cases also by X-ray diffraction
报道了使用锌催化有效合成各种取代的 2-芳基-2,3-二氢-1H-perimidines。通过从反应混合物中简单过滤,可以高产率地分离出一系列具有各种官能团的 2,3-二氢脒脒。新化合物已通过光谱和光谱分析以及在某些情况下通过 X 射线衍射进行了充分表征。随后还对合成方法进行了二、三和四(水杨基)醛试剂的测试,并以良好的产率提供了相应的多脒。在本研究中,还发现了一种意想不到的双 (2,3-二氢-1H-perimidine) 分解产物。
