## Abstract 2‐Hydroxy‐2′‐alkylthio‐1,1′‐binaphthyl compounds are catalytic promoters of the 1,4‐addition of AlMe~3~ to linear aliphatic enones in THF at βˆ’40 to βˆ’48 °C in the presence of [Cu(MeCN)~4~]BF~4~. At ligand loadings of 5–20 mol %, enantioselectivities of 80–93 % are realised for most subst
