Throughout the development of organocatalysis, privileged catalysts, i.e. catalysts which catalyse a wide variety of different reactions through the same mechanism of enantioinduction, have emerged in multiple organocatalytic transformations . The examples discussed in section 3 all have seen the application of ML techniques to predict the selectivity of a reaction of interest. However, since the mechanism of enantioinduction is similar for multiple reactions catalysed by a privileged catalyst class, these 'related' reactions can in principle be modelled together. The reactions are assumed to be mechanistically transferable.
