point: A simple primary amine thioureacatalyzed highly enantioselectiveconjugateaddition of α,α‐disubstituted aldehydes to maleimides has been developed. The biologically useful chiral disubstituted α‐branched succinimides are attained with the generation of two contiguous quaternary and/or tertiary stereogenic centers in one step with excellent enantioselectivities and in high yields under mild
