A One‐Pot Enantioselective Chemo‐Enzymatic Synthesis of Amino Acids in Water

The combination of immobilised Rh‐MonoPhos (1‐AlTUD‐1) and acylase I afforded a chemo‐enzymatic, one‐pot process for the enantioselective synthesis of amino acids in water, without the need for isolation of intermediates. In addition, the enzymatic hydrolysis increases the enantiopurity of the product from 95% ee to >98% ee. Compatibility studies revealed that for optimum results compartmentalisation of the catalysts is required.
