  • Chelate-controlled diastereoselective hydrogenation with heterogeneous catalyst
    Patent number: 10000460
    Abstract: A hydrogenation catalyst, preferably palladium on a support, preferably alumina or activated charcoal support, is used in the presence of lithium salts, with salts such as the borates being preferred. This provides hydrogenation of precursors to give rise to a stereoselective, such as diastereoselective bias in the product of alkene hydrogenation using the catalyst.
    Type: Grant
    Filed: March 27, 2017
    Date of Patent: June 19, 2018
    Assignee: Thomas Swan & Co. Ltd
    Inventors: David Dunn, Howard Winston Tyrrell Sutton, John Ing Chuan Daly, Simon Jonathon Grant, Lian Hutchings, Patrice Georges Antonin Ribiere, Matthew Richard Gibbings, Sergio Aaron Gamboa Martinez, Craig Anderson, Yulia Rogan
