Abstract A ruthenium based catalytic system ([Ru(p-cymene)Cl2]2/XantPhos with substoichiometric Cs2CO3) has been established to effectively achieve the first direct amination cyclization of 1,2,4-butanetriol with primary aromatic amines. The product of this sustainable hydrogen autotransfer process is valuable N-aryl-3-pyrrolidinol.
摘要建立了钌基催化体系([Ru(p-cymene)Cl2] 2 / XantPhos和亚化学计量的Cs2CO3),以有效地实现1,2,4-丁三醇与伯芳族胺的首次直接胺化环化。这种可持续的氢自动转移过程的产物是有价值的N-芳基-3-吡咯烷醇。
