Based on the recently reported asymmetric hydrogenation of methyl acetoacetate in a continuous-flow, gas phase reaction using Supported Ionic LiquidPhase (SILP) catalysis, this study deals with the even more challenging asymmetric reduction of the α-keto ester methyl pyruvate. Different support materials, ligands and ionic liquids were screened to identify an optimized Ru-based SILP catalyst. With
