The synthesis of pyrrolidinones from reductive amination of levulinic acid (LA) with primary amines is reported. Pyrrolidinones have various applications such as surfactants, pharmaceutical intermediates, dispersants, and solvents. The half‐sandwich Cp*Ir complex (Cp* is 1,2,3,4,5‐pentamethylcyclopenta‐1,3‐diene) coordinated by bipyridine ligand bearing both dimethylamino and ortho‐hydroxyl groups
报道了由乙酰丙酸(LA)与伯胺的还原胺化反应合成吡咯烷酮。吡咯烷酮具有各种应用,例如表面活性剂,药物中间体,分散剂和溶剂。夹有二甲氨基和邻羟基的联吡啶配体配位的半三明治Cp * Ir配合物(Cp *为1,2,3,4,5-戊甲基环戊-1,3-二烯)显示出对还原胺化的高催化活性洛杉矶 一系列伯胺,例如芳族和苄基胺,很容易以良好的产率转化为相应的吡咯烷酮。
