Annotation	In this study, we focused on the application of a microfluidic chip reactor to the stereoselective hydrogenation of achiral methylacetoacetate (MAA) to isomeric (R)-(+) or (S)-(-)-methyl-3-hydroxybutanoate (MHB) over a chiral ([RuCl((R)-BINAP)(p-cymene)]Cl) complex immobilized in the mixed [N8222][Tf2N]/methanol/water solvent phase. A presence of ionic liquid (quarternary ammonium salt) has a potential for an easy separation of this catalyst via its pseudo-immobilization. The reaction has been successfully carried out in such an arrangement with a very high conversion of MAA (above 97%) also reaching a very high enantioselectivity (above 99%) towards the (R)-(+)-methyl-3-hydroxybutanoate isomer.
