## Abstract The first organocatalytic asymmetric aza‐Friedel–Crafts reaction of naphthols with __N__‐sulfonyl imines has been developed. The cupreine‐derived bifunctional organocatalyst BzCPN efficiently catalyzes the formation of aza‐Friedel–Crafts products in good to excellent yields (up to 99 %)
## Abstract The bifunctional chiral thiourea—tertiary amine THU derived from cinchonine catalyzes the alkylation of sesamol and 2‐substituted derivatives with aromatic nitro olefins with up to 90% enantioselectivity.
