Pd/Zn(OTf)2 Co‐Catalyzed Asymmetric Hydrogenation of Imines under Normal Pressure of Hydrogen

An efficient method for the asymmetric hydrogenation of cyclic and acyclic N‐sulfonylimines co‐catalyzed by Pd/Zn(OTf)2 using hydrogen gas under ambient pressure was developed. The methodology offers an easy access to generate chiral sulfonylamines in good yields and excellent enantioselectivities....

Description
Summary:An efficient method for the asymmetric hydrogenation of cyclic and acyclic N‐sulfonylimines co‐catalyzed by Pd/Zn(OTf)2 using hydrogen gas under ambient pressure was developed. The methodology offers an easy access to generate chiral sulfonylamines in good yields and excellent enantioselectivities. Chiral sulfonylamines can be efficiently synthesized in good yields by asymmetric hydrogenation of cyclic and acyclic N‐sulfonylimines co‐catalyzed by Pd/Zn(OTf)2 using hydrogen gas under ambient pressure.
