A chiral spirocyclic borate ligand as a catalyst for the enantioselective Nozaki-Hiyama-Kishi allylation of arylaldehydes

A chiral spirocyclic borate catalyst was used in the enantioselective Nozaki-Hiyama-Kishi allylation of arylaldehydes to determine the relationship between enantioselectivity and the Hammet constant for the production of homoallyl alcohols.
