Chemoenzymatic Cascades Combining Biocatalysis and Transition Metal Catalysis for Asymmetric Synthesis

Abstract

The combination of catalytic methods provides multiple advantages in organic synthesis, allowing access to diverse organic molecules in a straightforward manner. Merging metal and enzyme catalysis is currently receiving great attention due to the possibility to assemble metal catalysis in C-C coupling, olefin metathesis, hydration and other reactions with the exquisite stereospecificity displayed by enzymes. Thus, this minireview is organized based on the action of the metal species (Pd, Ru, Au, Ir, Fe…) in combination with different enzymes. Special attention will be paid to the design of sequential processes and concurrent cascades, presenting solutions such as the use of surfactants or compartmentalization strategies for those cases where incompatibilities could hamper the overall process.
