The synthesis of 2,3‐dihydroquinazolin‐4(1H)‐ones in a one‐pot cascade manner (nitrile hydration, nitro‐reduction, imine formation, and cyclocondensation) is reported. Glucose, a renewable resource, can be easily obtained from abundant lignocellulosic biomass and was employed as a mild reductant in alkaline aqueous medium with 2‐nitrobenzonitrile.
据报导,以一锅级联方式(腈水合,硝基还原,亚胺形成和环缩合)合成2,3-二氢喹唑啉-4(1 H)-1 。葡萄糖是一种可再生资源,可以很容易地从丰富的木质纤维素生物质中获得,并被用作带有2-硝基苄腈的碱性水介质中的温和还原剂。
