products enantioselectively but also in some cases there are hardly any instances of a catalytic enantioselectiveaddition of a carbon-based nucleophile (e.g., one enzyme-catalyzed aldol addition involving trichloromethyl ketones, and none with dichloromethyl, tribromomethyl, or dibromomethyl ketones). The approach is scalable and offers an expeditious route to the enantioselectivesynthesis of versatile
