functionalization of acyl heterocycles through a hydrogen‐atom transfer (HAT) process and the use of tailor‐made ketimines as reliable electrophilic partners. This transformation is translated into an enantiomerically controlled radical/polar cascade reaction in which water is produced as the sole by‐product and stereoselectivity is dictated by coordination to a chiral‐at‐rhodium catalyst.
