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.

In the presence of chiral catalytic complexes prepared from In(OTf) 3 and chiral PYBOX ligands, allytributylstannane reacted with aldehydes in ionic liquids to afford the corresponding homoallylic alcohols in high enantioselectivities (86-94% ee) and good yields (68-89%); the chiral catalysts immobilized in ionic liquids could be reused with comparable enantioselectivities and yields.

A new convenient method for the asymmetric transfer allylation of aromatic aldehydes was developed. The reaction gave the best results using a chiral allyl donor molecule derived from (-)-menthone in the presence of heteropoly acids supported on silica gel under solvent-free conditions, and the desired homoallylic alcohol derivatives were obtained in good yields with good to high enantioselectivity.

(Chemical Equation Presented) A chiral indium(III) - PYBOX complex prepared from indium triflate and chiral PYBOX has been discovered to effect high enantioselectivities in the addition of allyltributyl stannane to aldehydes. The allylation of a variety of aromatic, α,β-unsaturated, and aliphatic aldehydes resulted in good yields and high enantioselectivities (up to 94% ee).
