combination of a racemic catalyst with a scalemic substrate, we have recently developed a method for determining the enantioselectivity of a chiralcatalyst from its racemic form by massspectrometricscreening of a non‐equal mixture of two mass‐labeled quasi‐enantiomeric substrates. After an initial proof of principle using palladium‐catalyzed allylicsubstitution as test reaction, we report now the successful
