The synthesis of several pyrrolidones (PYR), including a highly complex tetracyclic one (40‐91% yields), is described employing an inexpensive iron catalyst and aqueous solutions of biomass‐derived levulinic acid (LA) and formic acid (FA). The method is broad since it works with many structurally different amines. Considering that all produced LA from a real biorefinery facility will most probably be further derivatized directly from the hydrolysed biomass in aqueous solutions (without isolation), this method furnishes many advantages when compared to previous ones that employ different solvents or neat LA.

铁蛋白和甲酸水溶液的铁催化还原胺化:一种在生物精炼厂选择性生产吡咯烷酮的方法
描述了几种吡咯烷酮(PYR)的合成,包括高度复杂的四环吡咯烷酮(40-91%的收率),它使用廉价的铁催化剂以及生物质衍生的乙酰丙酸(LA)和甲酸(FA)的水溶液进行合成。该方法是广泛的,因为它可与许多结构不同的胺一起使用。考虑到从真正的生物精炼厂生产的所有LA最有可能直接由水溶液中水解的生物质直接衍生化(不分离),与以前采用不同溶剂或纯LA的方法相比,该方法具有许多优势。
