Catalytic asymmetric synthesis of β-triazolyl amino alcohols by asymmetric transfer hydrogenation of α-triazolyl amino alkanones

Add time:08/18/2019    Source:sciencedirect.com

The synthesis of optically active β-triazolyl amino alcohols was carried out via ruthenium catalyzed asymmetric transfer hydrogenation of α-triazolyl amino alkanones. This reaction proceeds under mild reaction conditions with up to 99% yield and 99.9% enantiomeric excess (ee). This protocol was applied to the synthesis of an enantiopure antitubercular agent and its arylated product with retention in enantiomeric purity. The absolute configuration at the stereogenic center of the chiral product as found to be (S).
