Development of Asymmetric Transfer Hydrogenation with a Bifunctional Oxo-Tethered Ruthenium Catalyst in Flow for the Synthesis of a Ceramide (<scp>d</scp>-<i>erythro</i>-CER[NDS])
development of an efficient synthetic route for an opticallyactive ceramide compound (d-erythro-CER[NDS]) is described. The route proceeds through asymmetric transfer hydrogenation in a pipes-in-series flow reactor with oxo-tethered ruthenium complex-catalyzed dynamic kinetic resolution. This synthesis was accomplished without any expensive reagents, and none of the intermediates required isolation
