The unique handedness of the essential molecules of life and the key role of homochirality in the development of new drugs [1] is a source of inspiration for numerous efforts to design efficient catalytic procedures to prepare single enantiomers of biologically active compounds.[2] The analysis of the enantioselectivity in the (high-throughput) screening of asymmetric catalysts [3] is often the rate-determining step,[3, 4] despite the introduction of ...
