inexpensive method using microwave-assisted irradiation with Ni2B for the syntheses of aromatic amines, pyrrolobenzodiazepines as well as pyrroloquinazolinones was developed. This protocol was applied in the tandem resin-cleavage, azido reduction, and cyclization of compounds 3 and 5 that afforded substituted pyrrolo[2,1-c][1,4]benzodiazepines 4 and 6 in a one-pot manner. The microwave-assisted irradiation
开发了一种高效且廉价的方法,该方法使用微波辅助的Ni 2 B辐射来合成芳族胺,吡咯并苯并二氮杂pine以及吡咯并喹唑啉酮。该方案适用于串联式树脂裂解,叠氮基还原和化合物3和5的环化反应,这些化合物以一锅方式提供取代的吡咯并[2,1- c ] [1,4]苯并二氮杂卓4和6。与常规的热反应相比,微波辅助的辐射反应以非常短的反应时间提高了产率。 吡咯并[2,1- c ] [1,4]苯并二氮杂卓-吡咯并喹唑啉酮-叠氮还原环化-硼化镍-微波辐射
