Asymmetric reductive amination of β-keto amides catalyzed by the chiral catalyst Ru(OAc)2((R)-dm-segphos) produces unprotected β-amino amides with high yields and high enantioselectivities (94.7?99.5% ee). This “one-pot” methodology is general in substrate scope and has been successfully employed to produce sitagliptin with 99.5% ee and 91% assay yield. The excellent reaction efficiency is attributed to the remarkable tolerance to high concentrations of ammonium ion, the high chemoselectivity, and the high enantioselectivity (99.5% ee) of the Ru catalyst system.
期刊介绍:
The flagship journal of the American Chemical Society, known as the Journal of the American Chemical Society (JACS), has been a prestigious publication since its establishment in 1879. It holds a preeminent position in the field of chemistry and related interdisciplinary sciences. JACS is committed to disseminating cutting-edge research papers, covering a wide range of topics, and encompasses approximately 19,000 pages of Articles, Communications, and Perspectives annually. With a weekly publication frequency, JACS plays a vital role in advancing the field of chemistry by providing essential research.
